PATHOLOGY OF VASCULAR SKIN LESIONS - PART 3 pps

54 Sangüeza and Requena / Pathology of Vascular Skin Lesions The bone lesions are radiologically translucent and histopathologically consist of enchon- dromas. Of prime importance is the risk of malignant transformation of the enchondromas into chondrosarcomas, which occur in approximately 15% of the patients (21). Other cutaneous lesions described in patients with Maffucci’s syndrome include café- au-lait macules (22) and cystic lymphatic malformations (23). In addition to chondro- Fig. 16.

Venous malformations are also prominent in and are the main cutaneous manifesta- tion of Klippel-Trenaunay syndrome. The dominant features of this syndrome include cutaneous capillary and venous malformations, congenital varicose veins, and hypertro- phy of the involved limb (26) (Fig. 17). When, in addition to the aforementioned features, there is an arteriovenous fistula, the disorder is termed Parkes Weber syndrome (27). Klippel-Trenaunay syndrome affects males and females equally. Most commonly the malformation is unilateral, and the lower limb is the most commonly involved area. However, in rare cases the upper and lower limbs or the upper limb alone are affected; bilateral involvement has also been reported, and occasionally the disease affects the entire trunk. Regardless of the location, the malformation is present at birth, although it may not be clinically apparent at that time. Almost all reported cases are sporadic, although a few cases with a familial tendency have been described (28). Cutaneous lesions of Klippel-Trenaunay syndrome may consist of one or several port wine stains over the affected limb (26,27,29–35), but in addition, it is common to find Fig. 17. (A) Venous malformation involving the entire lower right extremity in a patient with Klippel-Trenaunay syndrome. (B) Close-up view of the lesions involving the leg. 05/Sangüeza/27-72/F 01/14/2003, 11:21 AM55 56 Sangüeza and Requena / Pathology of Vascular Skin Lesions large venous ectatic vessels and vesicular lymphatic lesions (36). These vascular malfor- mations do not blanch significantly under pressure. In many cases varicosities are asso- ciated with the venous malformations. The varicosities start from a plexus of veins of the dorsum and lateral side of the foot and extend up a variable distance on the leg. Incom- petent perforating veins and deep vein abnormalities, which consist of occlusion by a fibrous band, agenesis, or atresia, are also seen in these patients. The involved limb is usually hypertrophic, and this enlargement is mostly caused by muscle hypertrophy, thickened skin, excessive subcutaneous fat, the bulkiness of the abnormal vascular tissue, and sometimes concomitant lymphedema. Usually there is little increase in bone diam- eter in the hypertrophic limb. Patients with this syndrome occasionally complain of profuse sweating of the skin involved in the vascular malformation, and the affected areas may also feel warmer than normal. Other systems and organs may show abnormalities in patients with Klippel-Trenaunay syndrome (37); these anomalies usually occur within or adjacent to the area involved by the vascular malformation. They can affect any mesodermal and ectodermal structure, suggesting a more generalized dysplasia of the structures subject to a common teratoge- nic influence. Venous thrombosis is common in patients with Klippel-Trenaunay syn- drome, and therefore these patients have frequent episodes of pulmonary embolism. The simultaneous occurrence of Klippel-Trenaunay syndrome and Fabry’s disease has been described in the same patient (38). Gorham’s syndrome (39) is a rare, nonfamilial disorder, that affects both sexes equally. It is characterized by the development of venous and lymphatic malformations in the skin, mediastinum, and bones (40,41). The osseous lesions cause osteolysis with fibrosis and may lead to the disappearance of entire bones. Roentgenograms demonstrate lytic lesions on the involved bones with little or no sclerosis. Cutaneous lesions usually develop in the areas adjacent to the involved bones and may be accompanied by local muscular atrophy. Usually, Gorham’s syndrome is self-limited (42), although an aggressive vari- ant with a poor prognosis has been described (43). Bannayan-Zonana syndrome is a rare autosomal dominant disorder characterized by benign macrocephaly, lipomas, and cutaneous and visceral vascular malformations (44). The cutaneous lesions are usually deeply situated, bluish nodules (45–47), but lesions resembling superficial lymphatic malformations and angiokeratomas have also been de- scribed (48). Visceral involvement may be massive, resulting in life-threatening obstruction of vital organs, including the gastrointestinal tract and the central nervous system (48). The macrocephaly is not associated with hydrocephalus, and most patients remain intellectually normal, although mental retardation has been described in some cases (49). Riley-Smith syndrome is an autosomal dominant condition described in five members of the same family. It consists of macrocephaly without hydrocephalus, pseudo- papilledema, and cutaneous capillary, venous, and lymphatic malformations (50). Cutaneous vascular lesions may be present either at birth or appear shortly thereafter. The abdominal wall, hands, feet, and thighs are the most commonly involved sites. The patients remain intellectually and neurologically normal. This syndrome is similar to the Bannayan-Zonana syndrome, except that patients with the Riley-Smith syndrome have pseudopapilledema and do not have systemic lipomatous lesions. In 1980, Ruvalcaba et al. (51) described two male patients thought to be affected with hamartomatous intestinal polyps and spotted pigmentation of the penis. Based on the description of these two patients and other cases from the literature (52,53); Cohen (54) 05/Sangüeza/27-72/F 01/14/2003, 11:21 AM56 Chapter 5 / Cutaneous Vascular Malformations 57 suggested that the condition described by Ruvalcaba et al. (51) was a distinctive entity and coined the name Ruvalcaba-Myhre syndrome. Since then, additional cases have been reported under the name of Ruvalcaba-Myhre-Smith syndrome (55–57). In 1988, Dvir et al. (58) described a boy with macrocephaly, pseudopapilledema, lipoangiomatosis, and spotted pigmentation of the penis. Because the patient had clinical features of three syndromes (Bannayan-Zonana, Riley-Smith, and Ruvalcaba-Myhre-Smith), the authors proposed that the three conditions were simply different expressions of a single heredofamilial disorder. Cohen (59) supported this unifying theory and suggested that the “new” syndrome be named after the first authors of the three original reports, i.e., Bannayan-Riley-Ruvalcaba syndrome. Subsequently, additional reports of Bannayan- Riley-Ruvalcaba syndrome have appeared in the literature, lending further support to the unifying concept (60–62). Recently, patients with Bannayan-Riley-Ruvalcaba syndrome and facial tricholemmomas have been described, raising the possibility that Bannayan- Riley-Ruvalcaba syndrome and Cowden disease may represent different alleles at the same genetic locus or mutations of two genes in a common pathway (62). Other rare miscellaneous syndromes that may show cutaneous venous malformations include zosteriform venous malformations grouped in a unilateral dermatomal distribu- tion (63,64); hereditary neurocutaneous vascular malformations syndrome (65), which is transmitted as an autosomal dominant trait and it is characterized by the presence of multiple cutaneous vascular malformations associated with intracranial arteriovenous malformations; venous malformations on the face and anterior trunk associated with sternal cleft and atrophic scar on the median abdominal raphe (66); retroauricular hemangiomatous branchial clefts associated with several facial and neurosensorial anomalies (67); sacral vascular malformations associated with renal, genital, osseous, and neurologic malformations (68); cutaneous vascular malformations associated with vascular anomalies of the retina and optic nerve (69); and several members of a family affected by venous malformations involving the mouth, skin, and soft tissues, inherited as an autosomal dominant trait and with no other associated anomalies (70). H ISTOPATHOLOGIC FEATURES Histopathologically, venous malformations generally consist of ectatic blood vessels of irregular size and shape involving the deep dermis and subcutaneous fat (Fig. 18). Some of the involved blood vessels show thin walls, whereas others exhibit a thick layer of smooth muscle in their walls. Thrombosis and phleboliths are common, and areas of extravasated erythrocytes, deposits of hemosiderin, and extravascular calcifications are also frequent findings. Some of the cutaneous lesions of the aforementioned complex syndromes associated with venous malformations may show specific histopathologic features. Large blue fa- cial lesions with the clinical appearance of venous malformations showing glomus cells surrounding the vascular structures are better interpreted as glomangiomas (2). In some patients with blue rubber bleb nevus, the cutaneous lesions may also show multiple glomangiomas (18,71–73). The gastrointestinal lesions of patients with blue rubber bleb nevus show similar histopathologic features to those of the cutaneous lesions. The case described as “blue rubber bleb nevus with vascular lesions suggesting a link to the Osler- Rendu-Weber syndrome” (74) is better interpreted as an example of blue rubber bleb nevus with telangiectatic cutaneous lesions but not related to the Osler-Rendu-Weber syndrome. 05/Sangüeza/27-72/F 01/14/2003, 11:21 AM57 58 Sangüeza and Requena / Pathology of Vascular Skin Lesions Histopathologically, the cutaneous lesions of Maffucci’s syndrome consist of large, blood-filled vascular channels lined with flat endothelial cells. The walls of the vascular spaces vary from thin, delicate, irregularly outlined walls to thick, fibrous, and smooth Fig. 18. Histopathologic features of a venous malformation.

Several cases of spindle cell hemangiomas in patients with Maffuci’s syndrome have been described (75–83). Spindle cell hemangioma consists of well-circumscribed but not encapsulated nodules that combine features of hemangioma and Kaposi’s sarcoma. Dilated blood vessels appear as thin veins that sometimes contain organized thrombi and phleboliths within their lumina. Interspersed among the dilated blood vessels there are fascicles of spindle cells mimicking Kaposi’s sarcoma, but within the fascicles there are also round cells with prominent vacuolated cytoplasm. Sometimes vacuolization of the cytoplasm of round cells is so marked that they may be mistaken for entrapped fatty tissue. Histopathologically, the cutaneous vascular lesions of patients with Bannayan-Riley- Ruvalcaba syndrome show different combinations of capillary, venous, and lymphatic malformations (51). T REATMENT Small venous cutaneous malformations may be treated by simple surgical excision, but in those cases in which the vascular malformation is associated with other internal abnormalities, a careful follow-up of the patient is required. It is usually impossible to remove large extensive venous malformations surgically without causing severe scarring and other complications. In those cases involving the limbs, elastic stocking use is man- datory and should be started early in infancy. Management of patients with blue rubber bleb nevus depends on the individual case. Resection of the involved bowel segment may be required in patients with recurrent melena and anemia. Painful cutaneous lesions of glomangiomas may be treated by excision, cryosurgery, or laser therapy (13). Patients with Maffucci’s syndrome require careful follow-up, with radiologic and histopathologic examination of any rapidly enlarging bone lesion for early diagnosis of chondrosarcoma. Surgical excision of the cutaneous vascular malformations may be indicated to improve the appearance of the patient. Spindle cell hemangioma is a benign lesion and excision is curative. Superficial venous varicosities of patients with the Klippel-Trenaunay syndrome may be treated by ligation and stripping to relieve the local pain, but recurrences are common (33). Before excision of the superficial veins, a radiographic exploration should be performed to demonstrate that there is neither absence nor hypoplasia of the deep venous system. Patients with Klippel-Trenaunay syndrome should receive antithrombotic prophylasis prior to any surgery owing to the high risk of thromboembolic complications (33). No effective treatment has been found for patients with Gorham’s syndrome, although radiotherapy may be helpful for bone pain. Patients with Bannayan-Riley-Ruvalcaba syndrome should be explored for detection of neurologic or any other associated internal malformation, and genetic counseling should be given to the family.

SUPERFICIAL CUTANEOUS LYMPHATIC MALFORMATIONS CLINICAL FEATURES Superficial cutaneous lymphatic malformations are localized lesions of the cutaneous, subcutaneous, or submucosal lymphatic vessels. These lesions have been referred to in the past as “lymphangiomas,” which is an inaccurate term. The lesions are usually present at birth or appear shortly thereafter; they can be located in any anatomic site but have a predilection for the axillary folds, shoulders, neck, proxi- mal parts of the extremities (Figs. 19 and 20), and tongue (1–3). Superficial lymphatic malformations (inaccurately termed “lymphangioma circunscriptum”) are the common- est variant of cutaneous lymphatic malformation. Clinically, the lesion consists of numerous small vesicle-like lesions, often with a verrucous surface, grouped in a plaque. Sometimes, owing to the presence of blood vessels, purplish areas can be seen within the lesion.
