Solid Renal Mass in a Transplanted Allograft Kidney: Mucinous Tubular and Spindle Cell Renal Cell Carcinoma.

Renal transplantation is the main treatment for end-stage kidney disease. Transplantation reduces the mortality rate and increases life quality in this population but cancer in allograft kidney is a major problem. Here, we report a 39-year male who had renal transplantation 10 years ago. On routine follow-up, radiologic imaging revealed a 32 mm mass in the allograft kidney. After partial nephrectomy, histopathologic examination revealed mucinous tubular and spindle cell variant of renal cell carcinoma(MTSCC). To our best knowledge, this is the first case in the literature that underwent partial nephrectomy in the transplanted kidney and was diagnosed with MTSCC. Key Words: Renal mass, Mucinous tubular and spindle cell tumor, Kidney transplantation.

A Giant Plunging Sublingual Dermoid Cyst Excised by Intraoral Approach.

OBJECTIVE: Dermoid and epidermoid cysts are rare cysts of the head and neck region, which should be considered in differential diagnosis of sublingual mass, constituting 0.01 % of all oral cavity cysts. There are suspected theories regarding the basis of the pathology. CASE REPORT: 30-year-old male referred to our clinic with a chief complaint of sublingual mass which had been present for many years but the lesion enlarged over the past 3 years. MRI examination revealed a giant cystic mass which was 3.6 × 3.9 mm in diameter and medially located at sublingual region. TREATMENT AND PROGNOSIS: Intraoral approach was preferred for surgery and no recurrence or complaints were detected during follow-up period. CONCLUSION: When a cystic mass is detected on the floor of oral cavity, we must consider dermoid cysts for differential diagnosis. Surgery is the only treatment. If possible, intraoral approach should be preferred because of its perfect cosmetic results.
