Hepatoid carcinoma of the ovary: A case report and review of the literature.

Primary hepatoid carcinoma of the ovary (HCO) is a rare aggressive tumor that typically presents at an advanced stage in postmenopausal women with unilateral or bilateral ovarian masses and elevated AFP and CA125. We report a case of HCO in a 73 year-old woman who presented with abdominal distention, weight loss, and a large lower abdominal mass. Postoperative serum AFP was markedly elevated and trended down with initiation of chemotherapy.

Lymphoepithelial cyst as a herald of HIV seropositivity in a patient with known history of neurocysticercosis and suspected parotid cysticercosis.

Among those with acquired immune deficiency syndrome, salivary gland pathology and other less common signs of human immunodeficiency virus (HIV) seropositivity are emerging. Generally speaking, lymphoepithelial lesions of the parotid gland are uncommon with a reported incidence of 0.6%, but they are beginning to overtake other oral lesions such as candidiasis as predominant oral manifestations of clinical HIV infection.

Concurrent renal-cell carcinoma and cutaneous leiomyomas: A case of HLRCC.

A 51-year-old Caucasian female presenting with renal-cell cancer and cutaneous leiomyomas was later diagnosed with Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC) Syndrome. HLRCC is an autosomal dominant condition caused by a mutation in the fumarate hydratase gene, which encodes for an enzyme in the citric acid cycle. This syndrome has been reported in over 100 families throughout the world, the majority of whom are of Eastern European descent.

Nasal chondromesenchymal hamartoma: radiographic and histopathologic analysis of a rare pediatric tumor.

Nasal chondromesenchymal hamartoma (NCMH) is an extremely rare benign pediatric tumor that was described in 1998. Only 19 cases are reported in the literature. We present a 15-year-old girl with nasal obstruction and recurrent sinusitis.
