Summary
Pseudoangiomatous spindle cell lipoma (PASCL) is a rare tumor. This study details six new cases, highlighting typical histological and immunohistochemical features, especially CD34 positivity, aiding diagnosis.
Area of Science:
- Dermatopathology
- Oncology
- Surgical Pathology
Context:
- Pseudoangiomatous spindle cell lipoma (PASCL) is a rare variant of spindle cell lipoma.
- Only nine cases have been previously reported in the literature.
- This study reviews six additional cases from 1987-2009.
Purpose:
- To describe the clinicopathological features of PASCL.
- To evaluate the diagnostic utility of immunohistochemistry in PASCL.
- To determine the frequency of PASCL among spindle cell lipomas.
Summary:
- Six cases of PASCL were reviewed, all occurring in males with a median age of 52.
- The median tumor size was 3cm, with four cases presenting in atypical locations (cheek, finger, elbow, jaw).
- Histological and immunohistochemical findings, particularly CD34 positivity, were consistent with previous reports and strongly suggestive of diagnosis.
Impact:
- This study expands the known cases of PASCL, contributing to a better understanding of this rare lipoma variant.
- The findings reinforce the importance of specific immunohistochemical markers, such as CD34, for accurate PASCL diagnosis.
- The reported atypical locations broaden the differential diagnosis for lesions in these sites.

Cirrhosis I: Introduction
Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
