Background: Nowadays, the incidence of skin cancer has increased, especially in the elderly population, probably due to increasing longevity and lifestyle changes. Sun exposure plays a pivotal role in the development of the skin tumors, among these basal cell carcinoma (BCC) is the most frequent with an incidence 4 times higher than that of squamous cell carcinoma (SCC) and it is 20 times more common than melanoma. On the other hand, skin adnexal tumors are extremely rare and hydroadenocarcinoma (HC) is generally considered a malignancy of eccrine cutaneous sweat glands. It occurs in 0.01% of skin cancers and often it can mimic other skin cancers, particulary BCC. Case presentation: An 84-year-old woman come to our attention for a neoformation on the upper lip. Seeing as she had previously undergone operations for removal of basaliomas on the face, the lesion was believed to be a recurrence. Facial and neck MRI and CT-scan analysis revealed that the lesion appeared in correspondence of the midline and paramedian site of the upper lip with extension into the left nasal cavity, not dissociable from the surrounding tissues. For this reason, the patient underwent an “en bloc” resection instead of Mohs' surgery. The definitive histological diagnosis concluded that the lesion was a hydroadenocarcinoma. Conclusion: In front of a nodular lesion of the skin it is always advisable to perform a biopsy to type the neoformation and also exclude rare tumors such us hydroadenocarcinoma.

Abstract

Background: Nowadays, the incidence of skin cancer has increased, especially in the elderly population, probably due to increasing longevity and lifestyle changes. Sun exposure plays a pivotal role in the development of the skin tumors, among these basal cell carcinoma (BCC) is the most frequent with an incidence 4 times higher than that of squamous cell carcinoma (SCC) and it is 20 times more common than melanoma. On the other hand, skin adnexal tumors are extremely rare and hydroadenocarcinoma (HC) is generally considered a malignancy of eccrine cutaneous sweat glands. It occurs in 0.01% of skin cancers and often it can mimic other skin cancers, particulary BCC. Case presentation: An 84-year-old woman come to our attention for a neoformation on the upper lip. Seeing as she had previously undergone operations for removal of basaliomas on the face, the lesion was believed to be a recurrence. Facial and neck MRI and CT-scan analysis revealed that the lesion appeared in correspondence of the midline and paramedian site of the upper lip with extension into the left nasal cavity, not dissociable from the surrounding tissues. For this reason, the patient underwent an “en bloc” resection instead of Mohs' surgery. The definitive histological diagnosis concluded that the lesion was a hydroadenocarcinoma. Conclusion: In front of a nodular lesion of the skin it is always advisable to perform a biopsy to type the neoformation and also exclude rare tumors such us hydroadenocarcinoma.
