Pseudo-Kaposi's Sarcoma: A Rare Case and Review

Our report concerns a 72-year-old female patient who presented with nodular ulcers on her right lower extremity and foot for a duration of 5 months. Based on the results of a dermatological examination, histopathological examination of the lesions, and immunohistochemical findings, we were able to diagnose the patient with Mari-type pseudocaposi sarcoma. Further research allowed us to clarify the distinction between this type of sarcoma and Kaposi's sarcoma, which will be crucial in devising an effective treatment plan for the patient as we continue to monitor her progress during clinical supervision.

Histopathology of Spindle Cell Vascular Tumors

Vascular tumors with a spindled morphology represent a diagnostic challenge in soft tissue pathology. It may be difficult to distinguish certain benign entities in this category from spindled vascular tumors of intermediate malignancy or even spindled variants of angiosarcoma. This article focuses on vascular tumors characterized by a predominantly spindled morphology, including spindle cell hemangioma, acquired tufted angioma (angioblastoma of Nakagawa), kaposiform hemangioendothelioma, Kaposi sarcoma, and spindle cell variants of angiosarcoma.
