Granular cell tumor in the perineum. A review and case report
Acta Obstetricia Et Gynecologica Scandinavica
|January 1, 1981
Abstract:
Granular cell tumor is a lesion which clinically often resembles a fibroma. The tumor is, however, frequently ill-defined, and it may be mistaken for a malignant growth. The granular cell tumor is only rarely located to the perineum. A total of 55 cases have been reported. The diagnosis can be obtained by frozen section microscopy. Recurrence is prevented by excising the whole lesion. The development of malignancy is extremely rare.
Insights
Granular cell tumors can mimic fibromas but may appear malignant. Early diagnosis via frozen section microscopy and complete excision prevent recurrence of this rare perineal lesion.
Area of Science:
- Oncology
- Pathology
Background:
- Granular cell tumors (GCTs) are rare neoplasms with uncertain histogenesis.
- Clinically, GCTs can present as benign-appearing lesions but may be ill-defined.
Observation:
- This study reviews 55 reported cases of granular cell tumors.
- A rare perineal location for GCTs is noted, with potential for misdiagnosis as malignancy.
- Frozen section microscopy is a valuable diagnostic tool.
Findings:
- Complete surgical excision is crucial for preventing recurrence.
- The development of malignancy from a granular cell tumor is exceptionally rare.
Implications:
- Accurate diagnosis through frozen section microscopy aids in appropriate management.
- Understanding the low malignant potential of GCTs is important for clinical decision-making.
- Complete excision ensures favorable prognosis and prevents local recurrence.
