RESUMEN

Symplasmic or atypical leiomyoma and lipoleiomyoma are two very rare morphological variants of leiomyoma of the uterus. Both the tumours show a benign behavior like the classical leiomyoma. But differentiated from the classical leiomyoma by presence of bizarre cellular pattern with paucity of mitosis and presence of mature lipocytes within a leiomyoma respectively. We report one case each of these variants in two routine fibroid uterus specimens of two different patients, as they can be misdiagnosed as leiomyosarcoma and well-differentiated liposarcoma respectively, by inexperienced pathologists.

RESUMEN

Angiomyolipomas are the most common benign mesenchymal tumours of the kidney. Most of the angiomyolipomas in adults are asymptomatic and discovered incidentally. We report a case in a symptomatic 55 yrs old male who had a huge retroperitoneal mass abdomen and in whom diagnosis and organ of origin remained unclear until operation and histopathological study was performed. Radiological and fine needle aspiration cytology (FNAC) report of a malignant retroperitoneal tumour was given, but histological examination of the respective tumorous mass showed a benign renal tumour - angiomyolipoma. Our emphasis by reporting this case is to make cytopathologists and radiologists aware of such kind of diagnostic pitfall encountered while reporting retroperitoneal masses.
