What causes bacillary angiomatosis?

Two Bartonella species, Bartonella henselae and Bartonella quintana, are responsible for bacillary angiomatosis. These species cause bacillary angiomatosis with varying clinical manifestations. While cutaneous lesions are caused by both species, B tends to cause more subcutaneous and osseous lesions.

How can you distinguish between bacillary angiomatosis and Kaposi sarcoma?

Capillary growth and neutrophilic inflammation are typical features of bacillary angiomatosis lesions. Kaposi sarcoma lesions, in contrast, show slit-like vascular spaces with lymphoplasmacytic infiltrates. The diagnosis must be established through a skin biopsy.

What is the Kaposi sarcoma’s pathophysiology?

The excessive proliferation of spindle cells, which are thought to have endothelial cell origins, is what leads to kaposi sarcoma. Although the tumors are heterogeneous, KSHV genomic material predominates and is accompanied by immunohistochemical markers of lymphoid, spindle, and endothelial cells.

What is Kaposi’s sarcoma’s differential diagnosis?

Bacillary angiomatosis, hemosiderotic hemangioma, fibrous histiocytoma, interstitial granuloma annulare, arteriovenous malformations, and pyogenic granuloma are possible diagnoses in the differential.
