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 rare cause of ileus: late jejunal stricture following blunt abdominal trauma.

Small intestinal stricture forming in the late phase following nonpenetrating abdominal trauma is rare cause of ileus. It has often been suggested that it is result of localized feeding deficiency on the intestinal wall related to minor trauma in the mesentery. Laparoscopy has been increasingly used for diagnosis and treatment. Diagnosis should be supported by pathological analyses in case of intestinal stenosis related to blunt abdominal traumas.

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.

Complicated Giant Pilomatrixoma of the Parotid Region.

OBJECTIVE: Pilomatrixoma (calcifying epithelioma of Malherbe) is a benign soft tissue tumour arising from dermis or subcutaneous tissue which should be considered in differential diagnosis of preauricular lesions especially when skin fixation is present. CASE REPORT: Twenty-three year old male referred to our clinic with complaint of left preauricular swelling over 18 months which enlarged and became painful in the last 2 months. Because the lesion showed signs of infection, surgery was planned after medical therapy was completed. FNAB suggest pleomorphic adenoma as preliminary diagnosis. US or MRI showed no specific feature. TREATMENT AND PROGNOSIS: Total excision, superficial parotidectomy with facial nerve sparing was performed after regression of infectious signs. Postoperatively no recurrence was detected. CONCLUSION: Pilomatrixomas are benign tumours but have diagnostic difficulties according to clinical and cytologic findings. This rare lesion should be kept in mind to avoid misdiagnosis as malign parotid tumours, particularly in the presence of skin change.

Profile of head and neck cancers in Dr. Lütfi Kirdar Kartal Educational and Research Hospital.

OBJECTIVE: Head and neck cancers account for 17.6% of all malignant neoplasms. Data on the incidence of head and neck cancers and histological subtypes in Turkey are limited. This study aimed to provide an overview of statistics for head and neck cancers. MATERIAL AND METHOD: This retrospective and descriptive study included 1973 cases of in-situ carcinomas, malignant and borderline neoplasia from the head and neck region in a period of 5 years, diagnosed at Dr.Lütfi Kirdar Kartal Education and Research Hospital's Department of Pathology. Demographic data of patients and data from histopathological report were recorded. The topography of all tumours was coded according to the International Classification of Diseases for Oncology, 2nd and 3rd edition and histological and behavioral codes were given according to ICD-O-3. Data was entered and analyzed using Microsoft Excel™, version 2010. RESULTS: Male and female ratio was 1.03 for head and neck cancers. The most common sites for males were described as the ratio in head and neck cancers and all malignant tumours as follows: the skin (non-melanoma) (48.4%-8.2%), the larynx (12.6%-2.3%), the thyroid (11.1%-1.2%), the lips (7.8%-1.3%), and the nasopharynx (3.1%-0.5%). The most common sites for females were as follows: the thyroid (45.3%-8.3%), the skin (non-melanoma) (39.6%-7.3%), the lips (3.6%-0.6%), the nasopharynx (2.2%-0.4%) and the eye (1.7%-0.3%). The male: female ratio was 25.2 for larynx cancers. The most common histological types and rates for males and females were also given. CONCLUSION: This descriptive epidemiological pathology-based cancer incidence study has relative value for describing head and neck cancer incidences in the Istanbul region and shown that pathology report-based descriptive epidemiological studies are still valuable for determination of the regional distribution of cancer incidence out of the active cancer registration regions.
