Benign cystic mesothelioma (BCM) is an uncommon lesion of the peritoneum occurring predominantly in women of reproductive age. Although most patients are managed by surgical resection, a reported high incidence of cyst recurrence has led to the use of hormonal therapy in isolated cases in an attempt to control cyst size and relieve local symptoms. To date,(More)
The majority of ovarian sex cord tumors with annular tubules (SCTAT) are benign neoplasms that arise sporadically. In patients who have Peutz-Jeghers syndrome (PJS), ovarian SCTAT is often an incidental finding. Malignant behavior in SCTAT has heretofore been reported only in sporadic cases. We report a case of bilateral, malignant SCTAT developing in a(More)
The fine-needle aspiration biopsy (FNAB) findings in two cases of hemangiopericytoma (HP), arising in the parotid gland and on the inner chest wall, respectively, are reported. Smear preparations in each case showed cytologic features of an undifferentiated spindle-cell neoplasm, whereas a core needle biopsy specimen of the chest wall mass showed a(More)
Metastatic, noncolorectal carcinoma involving the anal canal is exceptionally rare, with only 3 cases being described in the medical literature. We report the case of a 53-year-old man with an anal mass clinically presenting as a large, thrombosed, internal hemorrhoid. The patient had a history of nephrectomy for renal cell carcinoma 9 years previously. The(More)
CONTEXT The incidence of tall cell variant of papillary thyroid carcinoma that has metastasized to the pancreas is extremely rare. There has been only one previously reported case of pancreatic metastasis of the tall cell variant of papillary thyroid carcinoma. CASE REPORT We present the case of a patient who presented with tall cell variant of papillary(More)
Primary neuroendocrine tumors of the larynx are rare, with moderately differentiated neuroendocrine carcinoma (MDNC) being the most frequent histologic type. We report a MDNC in a 57-year-old gentleman with an enlarging right-sided neck mass. Flexible fiberoptic exam revealed a right arytenoid lesion. Histology from excisional biopsy was concerning for(More)
Primary cardiac lymphoma (PCL) is defined as a non-Hodgkin lymphoma involving only the heart or pericardium. PCL is extremely rare and often misdiagnosed. We report the case of a healthy 53-year-old male who originally presented with blurred vision secondary to a right intraocular mass. Enucleation of the eye confirmed a ciliary body melanoma and, upon(More)
Primary pulmonary sarcomas are uncommon neoplasms. Primary fibrosarcoma of the lung is extremely rare, and only 53 cases have been documented in the literature to date. To our knowledge, the diagnosis of primary lung fibrosarcoma by fine-needle aspiration cytology has never been reported. We report a case of pulmonary fibrosarcoma diagnosed by fine-needle(More)
Uterine carcinosarcomas are uncommon, aggressive neoplasms usually afflicting postmenopausal women. Histologically, they are characterized by the presence of both malignant epithelial and stromal cells. The latter may be either homologous or heterologous in nature. The cytologic diagnosis of carcinosarcoma via fine-needle aspiration (FNA) was previously(More)
