Giant Skull Tumor: A Benign Meningioma.

ABSTRACT: A 37-year-old male patient was complaining from painless forehead swelling, which started 5 years ago. Brain computed tomography scan and magnetic resonance imaging showed a large extradural mass compressing the both frontal lobes with skull bone infiltration, hyperostosis and enlargement. The patient was operated in 2 stages. In the first stage, the authors achieved separation for the tumor from the scalp and skull. In the second stage after 1 week, the authors continued with circumferential dural opening around the tumor and separation of the tumor from brain tissue. Duroplasty was performed by autologous fascia latta and skin flap was closed primarily. The specimen was received grossly as huge mass weighing 1530 g and measuring 39 × 16 × 12 cm. Histopathologic examination showed grade I meningioma extending beyond the skull to the surrounding soft tissue.

Radiological and Histological Correlation in Small Cell Neuroendocrine Carcinoma of the Breast: A Case Report.

BACKGROUND Primary breast small cell neuroendocrine carcinoma is a rare subtype of breast cancer with about 57 cases reported in the literature. This rare type of cancer represents about 0.1% of breast carcinomas. Recently, the World Health Organization defined this type of cancer as a separate entity from other breast cancer types. The diagnosis of this type of cancer in the breast is difficult because the histological pattern is similar to the small cell neuroendocrine carcinoma of other more common primary sites of origin, including the lung. CASE REPORT A 39-year-old woman presented to our hospital with a left breast mass and recurrent mastitis. Physical examination revealed a painless lump in her left breast with a brown-colored discharge from the nipple, and her child refused breastfeeding from the left breast. A high-density well-defined rounded mass was observed upon mammography in the upper lateral aspect of the left breast. This mass lesion appeared hypoechoic with no posterior acoustic shadowing on ultrasound scan. A core-needle biopsy of the mass was performed and the diagnosis of small cell neuroendocrine carcinoma was rendered after histopathologic examination. Positron emission tomography scanning was helpful in the exclusion of primary origin from other organ sites; thus, the primary breast origin of the tumor was confirmed. CONCLUSIONS This case report provides a comprehensive approach to diagnose this type of small cell carcinoma originating primarily in the breast. The suspicion of this type of breast cancer should be raised if there is presence of characteristic histopathologic findings with the exclusion of any primary origin from other organ sites by the help of imaging studies.
