Abstract
- BACKGROUND
Poroid neoplasms consist of classic poroma, hidroacanthoma simplex, dermal duct tumor, and poroid hidradenoma. Poroid neoplasms are not rare tumors in dermatology. However, studies of the clinicopathologic characteristics of poroid neoplasms in Korea are very limited.
OBJECTIVE
To investigate the clinicopathologic characteristics of poroid neoplasms in Korea.
METHODS
The clinicopathologic characteristics of forty three cases of poroid neoplasms were retrospectively analyzed.
RESULTS
Poroid neoplasms were diagnosed mostly in the sixth decade, without sex predominance. The most common site was the lower extremities, followed by the head & neck, the trunk, the sole, the palm, and the upper extremities. All cases were observed as a solitary lesion. Papule or nodule shape, verrucous surface, and erythmatous color were most common characteristics of poroid neoplasms. The two cases showed sebaceous differentiation. Some cases showed melanin pigmentations in the lesions or perilesional basal layer.
CONCLUSION
Our study will be a resourceful data of poroid neoplasms for dermatologists and pathologists.
