A hyalinizing trabecular adenoma (HTA) is a rare benign thyroid tumor of follicular epithelial cell origin with a trabecular-alveolar growth pattern and marked intratrabecular hyalinization. The cytological and histological features of HTA are very similar to those of papillary and medullary carcinomas of the thyroid. Therefore, an accurate diagnosis of HTA is important to avoid unnecessary and potentially harmful management of patients. However, the results of BRAF gene mutation analysis shown by many studies are distinctly different between HTAs and papillary thyroid carcinomas. Herein, we describe a rare case of HTA of the thyroid in a 49-year-old female and consider its characteristic cytological features and BRAF gene mutation analysis results with a brief review of the literature.

Abstract PDF

Carcinosarcoma of the salivary glands is a rare malignant tumor showing both malignant epithelial and mesenchymal components. Herein, we present a carcinosarcoma of the parotid gland in a 67-year-old man consisting of osteosarcoma and adenocarcinoma components with fine needle aspiration cytological findings. The tumor was composed predominantly of osteosarcoma and small areas of adenocarcinomatous components and a hyalinized nodule reminiscent of pleomorphic adenoma. The tumor showed infiltrative growth features with perineural, lymphatic, and vascular invasion. Despite postoperative adjuvant radiation therapy, multiple metastatic lesions occurred in the both lungs 5 months after surgery. As salivary gland carcinosarcoma has been known to demonstrate highly aggressive behavior, an accurate pathological diagnosis is prerequisite for appropriate treatment.

Abstract PDF

Carcinosarcoma of the stomach is a rarely occurring malignant biphasic tumor that consists of both carcinomatous and sarcomatous components simultaneously in a single tumor. The common carcinoma component is tubular or papillary adenocarcinoma and the mesenchymal sarcomatous components are variable and these include leiomyosarcoma, rhabdomyosarcoma, osteosarcoma and chondrosarcoma. However, neuroendocrine carcinomatous differentiation in the carcinomatous component is extremely rare. We present here a rare gastric carcinosarcoma that demonstrated neuroendocrine carcinomatous and leiomyosarcomatous differentiation in a 47-year-old man.

Abstract PDF: We describe herein a rare case of a laryngeal myxoma presenting as a nodule. Laryngeal myxomas involving the neck region, especially the laryngeal area, are quite rare. A 36-year-old male patient presented with a 2 month history of hoarseness. On laryngoscopic examination, there was a myxoid homogeneous transparent mass on the right vocal cord. On microscopic examination, the lesion was hypocellular and myxoid. The lesion showed stellate or spindle cells which were evenly dispersed in the poorly vascularized myxoid stroma. Although the incidence is extremely rare, a laryngeal myxoma should be considered in the differential diagnosis of laryngeal masses.

Abstract PDF: Hairy polyps are a rare malformations of bigerminal origin that comprise of both ectodermal and mesodermal elements. Meningothelial elements are an extremely rare pathologic finding in hairy polyps. Here we report a case of a hairy polyp with a meningothelial element, which originated from the hard palate. A 1-year-old boy was evaluated for an intraoral mass accompanied by multiple congenital anomalies. A small polypoid mass was noted at the midline of the hard palate. The lesion had central fibroconnective tissue with an unusual stromal component showing reticulated anastomosing pseudovascular patterns. Immunohistochemical staining of the cells lining the pseudovascular spaces and the interstitial cells revealed vimentin and epithelial membrane antigen positivity.

Abstract PDF: Cystic lymphangioma is also known as cystic hygroma, and this is a congenital malformation of the lymphatic system. Most lymphangiomas are present at birth and they are diagnosed by the age of 2. They are mostly located in the neck or axillary region. The breast as a site of origin is an extremely unusual location, and especially in adults. We report here on a case of cystic lymphangioma in a 36-year-old woman. Physical examination revealed a tender cystic mass in the upper outer quadrant of the right breast. Ultrasonography revealed an irregular hypoechoic mass lesion that was associated with irregular duct dilatation and several enlarged axillary lymph nodes. After the operation, the mass was revealed to be a cystic lymphangioma. Although it is very rare, cystic lymphangioma should be considered in the differential diagnosis of a breast mass in adults.
