Sebaceous Lymphadenoma of Parotid: Imaging, Cytological, and Histological Findings in Detail.

Sebaceous lymphadenomas are rare and account for less than 1% of primary salivary gland tumors. These rare tumors are mostly found in men older than 50 years. The clinicopathological features of these tumors are poorly understood and no definite causative factor has been reported for them till now.

Problem of foreign body in GI tract.

Most foreign bodies pass through the gastrointestinal tract uneventful. We report of a case of inadvertently ingested foreign body, which by endoscopy simulated a polyp and on biopsy reported as cancer, so the patient underwent an unnecessary major operation. This report emphasizes the importance of resemblance of foreign bodies with gastrointestinal neoplasm, and endoscopists, surgeons and pathologists should consider this entity in their daily practice.

Primary bilateral Burkitt lymphoma of the lactating breast: a case report and review of the literature.

Burkitt lymphoma (BL) is a highly aggressive neoplasm, which frequently affects the ileocecal region in the sporadic form and the jaw in the endemic form; however, the breast is a rare primary site of this tumor. Here we describe a case of primary bilateral breast BL presenting during lactation in a 23-year-old woman. Excisional biopsy of breast masses demonstrated a B-cell lymphoma with a characteristic 'starry sky' pattern highly suggestive of BL.

Sinonasal clear cell adenocarcinoma: a case report.

Background: Nonsalivary adenocarcinomas are the most interesting tumors found in the sinonasal area. They are rare tumors arising from surface epithelium. The clear cell type of this tumor is even more rare.

Visceral leishmaniasis: bone marrow biopsy findings.

Visceral leishmaniasis (VL) or Kala-azar is a common parasitic infection among children in Iran. The records of 249 children with VL were evaluated retrospectively. The clinical, hematologic, and bone marrow biopsy findings were studied.

Breast myeloma: a report of 3 cases with fine needle aspiration cytologic findings.

Background: Multiple myeloma of the breast is very rare, and the fine needle aspiration (FNA) findings have not been reported before.

Cases: Two cases of multiple myeloma presented with bilateral breast nodules during treatment with chemotherapy. One case of multiple myeloma presented initially with a left breast mass.

Peripheral blood and marrow findings in disseminated bacille Calmette-Guerin infection.

The authors describe an unusual case of a disseminated bacille Calmette-Guerin (BCG) infection in a 3-month-old girl who presented with a huge hepatosplenomegaly, fever, and pancytopenia. Clinically, an infantile kala-azar or lymphoma/leukemia was suspected. However, after thorough clinical and paraclinical investigations, the case was diagnosed as a disseminated BCG infection.
