Evaluation of Histologically and Histochemically Proven Cases of Vitiligo and its Correlation with CD4+ and CD8+ Lymphocyte Counts using Flow Cytometry.

Introduction: Vitiligo is an acquired cutaneous disorder characterized by progressive and selective destruction of melanocytes from the epidermis. Autoimmunity is strongly implicated in its pathogenesis. The destruction of melanocytes has a correlation with the peripheral blood lymphocyte imbalance mainly including Cytotoxic T cells (CD8+cells) and Helper T cells (CD4+cells).

Primary bilateral plasmablastic lymphoma of the testis in a human immunodeficiency virus positive man.

Human immunodeficiency virus (HIV)-related lymphomas are predominantly aggressive B-cells lymphomas. The most prevalent of the HIV-related lymphomas are diffuse large B-cell non-Hodgkin's lymphoma (NHL), which includes primary central nervous system lymphoma, and Burkitt lymphoma, whereas primary effusion lymphoma, plasmablastic lymphoma (PBL), and classic Hodgkin lymphoma are far less frequent. Of these, PBL is relatively uncommon and displays a distinct predilection for presentation in the oral cavity.

To evaluate the role of bone marrow aspiration and bone marrow biopsy in pancytopenia.

Background: Pancytopenia is not a disease entity but a triad of findings that may result from various disease processes, primarily or secondarily involving the bone marrow. Bone marrow aspiration and biopsy evaluation along with good clinical correlation is of utmost importance to evaluate the causes of pancytopenia and planning further investigations.

Aims: The present study was a prospective clinicohaematological study undertaken to analyse the various causes of pancytopenia by evaluating bone marrow aspiration and biopsy and correlating with clinical findings, complete blood counts and peripheral blood picture.

Primary chondrosarcoma of male breast: a rare case.

Sarcomas of the breast are relatively rare and account for 1% of all primary malignant tumors of the breast. Pure and primary chondrosarcoma of the male breast is an extremely rare tumor. It may arise either from the breast stroma itself or from underlying bone or cartilage.
