New fine structural observations in testicular malakoplakia: role of the Sertoli cell
Abstract:
A case of testicular malakoplakia is described in which cells other than histiocytes were involved in the tissue response. The abundant cell junctions, some closely related to mitochondria, and the peripheral displacement of rough endoplasmic reticulum by abundant phagolysosomes, suggest involvement of Sertoli cells, in addition to histiocytes. It is suggested that, perhaps, some forms of granulomatous orchitis and malakoplakia represent a single disease process observed at a different stage in its evolution.
Insights
This study describes testicular malakoplakia involving Sertoli cells alongside histiocytes. It suggests malakoplakia and granulomatous orchitis may represent stages of the same disease process.
Area of Science:
- Pathology
- Urology
- Cell Biology
Background:
- Testicular malakoplakia is a rare condition typically involving histiocytes.
- The cellular mechanisms and origins of malakoplakia are not fully understood.
Purpose of the Study:
- To describe a unique case of testicular malakoplakia involving non-histiocytic cells.
- To investigate the cellular morphology and potential origins of malakoplakia.
Main Methods:
- Histopathological examination of testicular tissue.
- Electron microscopy to analyze cellular structures.
Main Results:
- The case involved malakoplakia with significant involvement of cells beyond typical histiocytes.
- Ultrastructural analysis suggested the involvement of Sertoli cells, characterized by specific organelle arrangements and phagolysosome presence.
Conclusions:
- Testicular malakoplakia can involve Sertoli cells, expanding the understanding of cellular participation in this condition.
- Granulomatous orchitis and malakoplakia may represent different stages of a unified disease process.
