Radiotherapy in congenital vulvar lymphangioma circumscriptum

Congenital lymphangioma circumscriptum (LC) of the vulva is a rare disorder with unknown etiology. Treatment options include ablative approaches such as laser therapy, sclerotherapy, and surgery. Radiotherapy has been shown to be effective in the management of congenital lymphangioma especially in the thoracic and abdominal lesions. In this report, we describe a patient with persistent vulvar LC despite sclerosing therapy and several surgical excisions. She was treated with a course of external radiotherapy and showed a dramatic objective response with relief of all symptoms

Congenital plexiform schwannoma of the clitoris

Schwannomas are slow-growing nerve sheet neoplasms which are rarely found in the female genital system. In this article, we present a patient with Antony A congenital plexiform schwannoma of the clitoris. A 6-year-old girl was brought to our hospital with the history of a firm non-cystic clitoral mass from birth, which had been growing more rapidly during the previous year. The patient was scheduled for surgery. Histological studies revealed plexiform schwannoma of the clitoris post-operatively. Therefore, schwannoma should be considered in the differential diagnosis of clitoral masses.

Recurrent vulval congenital lymphangioma circumscriptum-a case report and literature review

Lymphangioma circumscriptum (LC) is a defect of lymphatics in deep dermis. This abnormal saccular dilatation of lymphatics occurs in dermal papillae visible as vesicles clinically. The entity may be acquired or congenital. The occurrence of congenital variety of LC in vulva is extremely rare, with only few cases reported in the literature. We communicate one such case presenting as recurrent vulval growth along with a review of literature and treatment modalities.

Rabdomiosarcoma botrioides congénito de vulva

Rhabdomyosarcoma is the most frequent malignant soft tissue tumor in pediatric patients; however, the vulvar location and congenital appearance are exceptional. We present the case of a newborn girl with botryoid rhabdomyosarcoma of the vulva, treated with chemotherapy, conservative surgery and autologous transplant. Botryoid rhabdomyosarcoma is a variation of embryonal rhabdomyosarcoma that typically grows in mucosa-lined hollow organs, from where it can spread to the body surface. The treatment of botryoid rhabdomyosarcoma in the genito-urinary area is based on polychemotherapy, and it can be complemented with radiotherapy and conservative surgery if necessary, thus resulting in an excellent prognosis and few long-term functional sequelae.

Congenital vulvar teratoma in a newborn

The most common site of teratomas in neonates is in the sacrococcygeal region. Herein the authors describe a congenital teratoma, and to their knowledge it is the first reported case of vulvar site in a newborn. Tumor was removed on the fourth day of life, and she was completely normal 18 months after the operation. Because of possible malignancy or recurrence, complete surgical excision of the tumor and careful follow-up is the treatment of choice. J Pediatr Surg 36:620-621.

Congenital epulis and granular cell tumor: a histologic and immunohistochemical study

OBJECTIVES

Although it is now reasonably certain that granular cell tumors derive from Schwann cells, the histogenesis of congenital epulis, which is largely isomorphic with granular cell tumor, remains unclear. A study was undertaken to compare the immunophenotype of these tumors with particular emphasis on the expression of matrix proteins and macrophage markers because such information is not available in the literature.

STUDY DESIGN

Four granular cell tumors and two congenital epulis were immunostained with a panel of 29 antibodies. Two congenital epulis and one granular cell tumor were investigated by electron microscopy, the latter also by immunoelectron microscopy.

RESULTS

Many similarities in immunostaining were found, for example, both tumor types were CD68+, Ki-M1P+, lysozyme-, vimentin+, fibronectin+, laminin+, lectin PHAE+, and lectin WGA+. However, differences were also noted, for example, granular cell tumor was always S100 protein+, but only one congenital epulis case was reactive (weak reactivity after microwave treatment), and staining with the proliferation markers anti-proliferating cell nuclear antigen and MIB 1 was found only in congenital epulis. Both tumor types exhibited pericellular and diffuse cytoplasmic staining for fibronectin and laminin.

CONCLUSIONS

The hypothesis that congenital epulis and granular cell tumor would exhibit similar reactivity for macrophage markers was confirmed: both were reactive with anti-CD68 and Ki-M1P and nonreactive with MAC387, anti-lysozyme, and 3A5. Intracytoplasmic staining for fibronectin and laminin, which has not been described previously in these tumors, appears to be a characteristic feature common to both tumors. This finding suggests that there could be a disturbance of synthesis and secretion of extracellular matrix proteins or a derangement of their receptor systems. This theory could be supported by the finding of intracytoplasmic CD49e-positive material in two cases.

Congenital hemangiopericytoma of the clitoris

Hemangiopericytoma is a rare vascular tumor that is believed to arise from the pericyte of Zimmermann. Approximately 10% of cases occur in children and a third are congenital. To our knowledge we report the first case of a congenital hemangiopericytoma arising from the clitoris, describe its management and review the literature.

Vulvar congenital dysplastic angiopathy

Congenital dysplastic angiopathy is a syndrome consisting of vascular angiomata, congenital varicosities, and trophic changes of the soft tissue and the skeleton. Frequently referred to as Klippel-Trenaunay or Klippel-Trenaunay-Weber syndrome, it rarely affects the female genitalia. An 18-year-old woman underwent evaluation and treatment for Klippel-Trenaunay syndrome with vulvar involvement. Preoperative evaluation included consultation with pediatric surgeons, gynecologic surgeons, and an interventional radiologist as well as individual and family psychological counseling. Attention to intraoperative detail resulted in minimal operative blood loss and preservation of normal anatomy. A postoperative hematoma was treated aggressively with surgical evacuation and drainage. Six-month follow-up revealed functionally and cosmetically normal vulvar anatomy.

Congenital dysplastic angiopathy (Klippel-Trenaunay-Weber syndrome) with vulvar involvement. A case report

Congenital dysplastic angiopathy (Klippel-Trenaunay-Weber Syndrome) consists of angiomata and congenital varicosities with trophic changes of soft tissues and various parts of the skeletal system. Involvement of female genitalia is rare and has been reported to occur in only four patients. The authors treated a patient with a lymphangioma of the vulva associated with congenital dysplastic angiopathy.
