Introduction:
Poroma and porocarcinoma (PC) are rare adnexal tumors with overlapping clinical features, making accurate diagnosis challenging.
Methods:
We retrospectively analyzed 46 histologically confirmed cases (37 poroma, 9 PC) diagnosed at a single center between 2010 and 2023, comparing demographic, clinical, and histopathological characteristics.
Results:
Poroma lesions were mainly located on the lower extremities, while PCs predominated on the trunk. Ulceration and bleeding were significantly more frequent in PCs. Among poromas, 24.3% involved the palmoplantar region; all volar lesions were skin-colored to pink-red and had higher clinical diagnostic accuracy than non-volar lesions.
Conclusion:
Lesion location, morphology, and color are key in evaluating adnexal tumors. Ulceration and bleeding should raise suspicion for PC, emphasizing the need for careful clinical assessment.
