1/54. Epithelioid sarcoma of the penis. Clinicopathologic study of a tumor with myogenic features and review of the literature concerning this unusual location.

    Soft tissue tumors of the penis are uncommon. We report here the clinicopathologic features of a penile epithelioid sarcoma (ES), review the literature concerning this unusual location and focalize our attention on its differentiation. The 34-year-old patient was admitted for abrupt urinary retention due to the growth of a firm and painful plaque on the left side of the shaft, three years previously clinically diagnosed as Peyronie's disease. Magnetic nuclear resonance revealed an infiltrating lesion of both corpora cavernosa. histology of bioptic fragments showed a nodular malignant spindle and epithelioid cell tumor with focal necrosis and relatively high mitotic rate. Based on the immunohistochemical data (cytokeratin , vimentin , EMA , CD34 , and S100-), the diagnosis of ES was strongly considered. Penectomy was undertaken and the diagnosis confirmed by both light and ultrastructural microscopy. The 22 month follow-up was free of recurrences and metastases. Although not dissimilar from the 10 previously described ES of the penis in terms of natural history and histology, the tumor reported here showed myogenic features as revealed by both immunohistochemistry (immunoreactivity for muscle specific actin) and ultrastructure (intercellular junctions, discontinuous basal lamina, pinocytotic vesicles and thin filaments with intercalated dense bodies). Although previously observed in ES of other sites, this feature has never been established in ES of the penis. ( info)

2/54. Development of Peyronie's and Dupuytren's diseases in an individual after single episodes of trauma: a case report and review of the literature.

    A case is presented in which a patient experienced the development of both Dupuytren's disease and Peyronie's disease after single episodes of sports-related trauma. These disorders and other fibromatoses are linked not only by similar pathologic features but by increased frequency of simultaneous occurrence. Some genetically predisposed individuals experience the development of the disorders after trauma or after some other factor unmasks that predisposition. A review of the literature with emphasis on the relationship between these fibromatoses and the varied nonsurgical attempts at treatment is presented. ( info)

3/54. Epithelioid sarcoma of the penis: report of an unusual case and review of the literature.

    Epithelioid sarcoma is a rare, slowly growing soft tissue tumor that uncommonly involves the penis, with only 11 previously reported cases. We present a case of penile epithelioid sarcoma in a 39-year-old man that mimicked Peyronie's disease, which was diagnosed 13 years following initial presentation. Preoperative magnetic resonance imaging showed multiple peripherally enhancing low signal intensity nodules involving the corpora cavernosa bilaterally. Following penectomy, histologic examination showed the typical features of epithelioid sarcoma, with a prominent pseudogranulomatous pattern. Immunohistochemically, the neoplastic cells demonstrated strong and diffuse staining for cytokeratins (AE1/AE3 and CAM 5.2), vimentin, epithelial membrane antigen, and CD34. Stains for S-100 protein, desmin, smooth muscle actin, and CD31 were negative. Electron microscopy demonstrated abundant intracytoplasmic intermediate filaments, scattered tonofilaments, and interdigitating filopodia. The present study is the first to describe magnetic resonance imaging and comprehensive immunohistochemical findings in penile epithelioid sarcoma. The majority of cases reported in the literature have demonstrated features similar to those typically found in epithelioid sarcoma involving the distal extremities. Consideration of epithelioid sarcoma in the differential diagnosis of a penile nodule or obstructive urinary symptoms may lead to early diagnosis and treatment. ( info)

4/54. Penile curvature associated with scleroderma.

    We present 2 cases of Peyronie's disease in patients with scleroderma. This association is uncommon, and our patients' symptoms and disease course differed from that typical for Peyronie's disease. We suggest a more conservative approach when treating patients whose penile curvature is associated with a systemic disease such as scleroderma. ( info)

5/54. Peyronie's disease as a complication of chronic graft versus host disease.

    Apart from one report of phimosis, involvement of the penis has not been reported as a complication of chronic GVHD. We report a patient with recurrent chronic GVHD who developed skin discoloration of the penile shaft, together with erectile dysfunction consistent with Peyronie's disease. Histological features were consistent with sclerodermatous change. These features suggest that the penis may be a target organ in chronic GVHD. ( info)

6/54. Peyronie's disease: an unusual presentation with butterfly shaped calcified plaques.

    Peyronie's disease is characterized by the formation of a fibrotic plaque in the tunica albugenia of the penis. Two patients with calcified butterfly shaped plaques involving the ventrolateral aspect of the penis are described. These patients were managed by plaque excision and dermal grafting with excellent post-operative results. ( info)

7/54. Epithelioid sarcoma of the penis--a rare differential diagnosis of Peyronie's disease.

    We report on a case of penile epithelioid sarcoma in a 29-year-old man presenting with a dorsal penile plaque that primarily was misdiagnosed as Peyronie's disease. Although the initial clinical findings of these two different entities appear similar, the consequence for the patient is severe. The only way of differentiating these disorders are histological findings. The principal microscopic characteristics of epithelioid sarcoma are the distinctive nodular arrangement, central degeneration and necrosis of the tumor cells with epithelioid appearance and eosinophilia. Immunohistochemical data (cytokeratin, epithelial membrane antigen, vimentin, CD 34, desmin) confirm the diagnosis. We conclude that in cases with slightest doubts on the diagnosis of Peyronie's disease, especially in younger men suffering from a fast-growing penile induration, a bioptic clarification of the entity should be performed to exclude a high malignant disease that can be only treated as far as it is localized by radical surgery.

8/54. Corporeal herniation after Nesbit plication with partial thickness shaving for congenital penile curvature.

    A 24-year-old man with penile congenital curvature who underwent partial thickness tunical shaving and plication with absorbable suture presented 1 month after surgery with a mass at the base of the right corpus cavernosum at the level of the original plication. We believe that corporeal herniation after tunical shaving and plication must be considered a complication of the technique independent from the type of suture used for the plicatures and probably related both to the opening of plications of the albuginea before permanent adhesion of the tunical layers, and to the decreased resistance of the albuginea, probably because of excessive shaving.

9/54. Development of Peyronie's disease during long-term colchicine treatment.

    colchicine has been reported to be a safe and effective medication in the treatment of early phase of Peyronie's disease (PD). However here we reported two patients, presenting with PD during high dose colchicine treatment for familiar mediterranean fever (FMF). ( info)

10/54. Peyronie's disease in men with hiv responding to highly active antiretroviral therapy.

    The pathogenesis of Peyronie's disease (induratio penis plastica) is unclear, but immune phenomena appear likely to be involved. Two cases are presented where the condition developed in temporal association with a virological response to highly active antiretroviral therapy (HAART) in men with hiv infection. It is suggested that this may represent another manifestation of immune restoration disease. ( info)
