Gottron's papules-like eruption developing under hydroxyurea therapy.

A 57-year-old white female developed a Gottron's papules (GP)-like eruption, without any of the other clinical or laboratory signs of dermatomyositis (DM). She was under hydroxyurea treatment for chronic myeloid leukemia at the time. Skin biopsy was compatible with seborrheic keratosis.

Low-grade renal collecting duct carcinoma. A case report with histochemical, immunohistochemical, and ultrastructural study.

We report a rare tumor called low-grade renal collecting duct carcinoma. Grossly, the tumor consisted of multiple cysts and solid white nodules, measuring 10 cm in diameter and occupying most of the renal parenchyma. Histologically, the tumor was characterized by well-differentiated tubules lined by eosinophilic cells without papillary projections, abundant predominantly extracellular mucin, minimal cellular atypia, no desmoplasia, and rare mitoses.

Human herpesvirus 8 in primary effusion lymphoma in an HIV-seronegative male. A case report.

Background: AIDS-related body cavity-based lymphoma, or primary effusion lymphoma (PEL), is a distinct clinicopathologic entity that occurs predominantly in immunosuppressed patients infected with human herpesvirus 8 (HHV-8), also known as Kaposi's sarcoma-associated herpesvirus. Although it rarely occurs in human immunodeficiency virus (HIV)-negative patients, we report such a case here.

Case: A 74-year-old male, who was HIV and Epstein-Barr virus (EBV) negative, was admitted to the hospital with dyspnea and chest pain.

Nonsyndromic paucity of interlobular bile ducts: report of 10 patients.

Objectives: Only a few reports of nonsyndromic paucity of interlobular bile ducts (NS-PILBD) have been published. The authors' aim was to outline the clinical and laboratory profile of patients with NS-PILBD diagnosed at a tertiary referral center.

Methods: The authors reviewed all the reports of pediatric liver biopsies performed between 1991 and 2000 at their institution.

Chromium-induced lymph node histiocytic proliferation after hip replacement. A case report.

Background: Prosthetic joint replacement is frequently used for the treatment of degenerative joint disease, rheumatoid arthritis, bone tumors and traumatic lesions. The prostheses contain such materials as titanium, cobalt and chromium. We describe a patient who, after total hip arthroplasty, developed an inguinal-pelvic mass.
