Labial metastasis of renal neoplasia - A diagnostic challenge.

INTRODUCTION: Cutaneous spread of solid visceral metastasis is very unusual presentation, usually in breast, lung, colon, ovarian carcinomas, and malignant melanoma. Less than 5% of cases of cutaneous spread are from renal neoplasms. PRESENTATION OF CASE: We present the case of a 48-year-old woman with a large lower lip tumor whose anatomopathological analysis of the lesion led us to identify a Clear Cell Renal Cell Carcinoma (ccRCC). DISCUSSION: The clinical manifestations of the ccRCC can be mild, generating a late diagnosis through metastasis of primary neoplasia. Their presentations can be varied, as described in this report. CONCLUSION: The knowledge of the different types of presentation of CCCR metastases can assist in decision making, but the progression of staging often only allows palliative measures.

Giant Perineal Solitary Fibrous Tumor: A Rare Case Report.

Background. Solitary fibrous tumor (SFT) is a fibroblastic mesenchymal tumor that was initially described from the pleura but currently arises at almost every anatomic site. It is usually benign, and surgical resection is curative. SFT involving the perineum is extremely rare. This is the third case report of a perineal SFT in the literature. Case Presentation. We reported an uncommon case of a 64-year-old man presenting with a huge perineal mass that started growing 3 years before his arrival in our service. He was asymptomatic. A contrast-enhanced CT scan revealed a heterogeneous well-circumscribed perineal mass with soft-tissue density. Invasion of the surrounding organs, distal metastasis, and lymph node swelling were absent. The complete resection of mass was done successfully. The specimen was a 23.0 × 14.0 × 8.0 cm encapsulated tumor. Mass weight was 1,170 g. After pathological analysis, we confirmed that the mass was a solitary fibrous tumor. The diagnosis was based on clinical findings and histological morphology and immunohistochemistry study. Conclusion. SFTs are usually indolent tumors with a favorable prognosis. The perineal location is extremely rare. Complete resection of the mass is the treatment of choice.
