Axillary extramammary Paget's disease (EMPD) is a rare condition with only a few cases reported in the literature. We performed a retrospective review and identified 16 cases of EMPD with axillary involvement. None of the patients developed recurrence or metastasis after surgery at a mean follow-up of 63.6 months. Axillary EMPD shares similar clinicopathological features with typical EMPD.
Co-occurrence of apocrine adenocarcinoma and invasive mammary-type ductal carcinoma in extramammary Paget disease of the axilla
Extramammary Paget disease (EMPD) is an uncommon malignancy that occurs in apocrine gland-rich areas of the body. EMPD of the axilla is rare, but a few cases have been reported. Some cases of EMPD have been reported with underlying apocrine adenocarcinoma; rarely, mammary-type ductal carcinoma can accompany EMPD. Here, we report a very rare case of EMPD with apocrine adenocarcinoma and invasive mammary-type ductal carcinoma.
Successful Intra-Arterial Chemotherapy for Extramammary Paget’s Disease of the Axilla in a Patient with Parkinson’s Disease
Extramammary Paget’s disease (EMPD) is a rare intraepithelial neoplasm occurring less frequently in men and even more rarely in the axilla. A 59-year-old man with severe Parkinson’s disease presented with axillary EMPD. The neurological comorbidity made treatment of the EMPD problematical and prompted us to propose locoregional intra-arterial chemotherapy in single short sessions. Two innovative chemotherapeutic macrocomplexes were used: doxorubicin incorporated in large liposomes and the taxane paclitaxel incorporated in albumin nanoparticles. A therapeutic response was seen right from the first treatment and was macroscopically close to complete after four cycles. Five months after the end of treatment the patient had minimal visible disease and had enjoyed a distinct improvement in quality of life, with no noteworthy complications related to the intra-arterial chemotherapy with percutaneous transfemoral catheterization.
