Basosquamous carcinoma: is it an aggressive tumor?

Area of Science:

• Dermatology
• Oncology
• Pathology

Background:

• Basosquamous carcinoma is a rare cutaneous tumor often perceived as aggressive.
• Existing literature suggests an increased risk of recurrence and metastasis, but with limited supporting data.
• Conflicting results in previous studies necessitate further clinical-pathological evaluation.

Purpose of the Study:

• To evaluate the clinical-pathological features of basosquamous carcinoma.
• To assess the follow-up outcomes in a series of patients treated for this condition.
• To provide a clearer understanding of basosquamous carcinoma's behavior and treatment efficacy.

Main Methods:

• Retrospective analysis of 35 basosquamous carcinoma patients who underwent surgical excision between 2000 and 2012.
• Review of medical files and re-evaluation of hematoxylin-eosin stained pathological sections by two pathologists.
• Tracking of outcomes including margin involvement, re-excision, local recurrence, and metastasis.

Main Results:

• The majority of tumors (94%) were located in the head and neck area.
• Margin involvement occurred in 31.4% of patients, necessitating re-excision.
• A low local recurrence rate of 4% was observed, with no regional lymph node or distant metastases reported in this series.

Conclusions:

• Basosquamous carcinoma exhibits a lower recurrence rate (4%) than often suggested in the literature.
• Surgical excision followed by regular follow-up is the recommended treatment approach.
• Further pathological studies are required for improved classification and consistent research outcomes.
