Neoplasms of Sweat Gland.

Area of Science:

• Dermatology
• Oncology
• Pathology

Background:

• Sweat gland tumors are rare skin appendages neoplasms.
• Understanding their incidence and types is crucial for diagnosis and treatment.

Purpose of the Study:

• To analyze the clinicopathological features of sweat gland tumors.
• To determine the prevalence and types of sweat gland tumors in a specific patient cohort.

Main Methods:

• Retrospective analysis of 50 cases of sweat gland tumors over a 27-year period.
• Histopathological classification of tumor types.
• Demographic data collection including age and sex.

Main Results:

• Sweat gland tumors constituted 54.34% of all skin appendage tumors.
• The 21-40 years age group had the highest incidence (47 cases), with a 1:1 male to female ratio.
• Common types included eccrine acrospiroma (13 cases), syringocystadenoma papilliferum (11 cases), and chondroid syringoma (11 cases).
• Three malignant cases were identified: two sweat gland carcinomas and one primary cutaneous mucinous carcinoma.

Conclusions:

• Sweat gland tumors are a significant proportion of skin appendage neoplasms.
• Eccrine acrospiroma, syringocystadenoma papilliferum, and chondroid syringoma are the most frequent benign types.
• Malignant sweat gland tumors, though rare, require prompt recognition and management.
