Paget disease is an intraepithelial neoplastic proliferation, commonly occurring in the breast and apocrine-rich areas, often associated with an underlying internal malignancy. Extramammary Paget disease (EMPD) of the oral cavity is exceedingly rare, with only eight reported cases, four of which were associated with an underlying internal malignancy. Here, we report a case of oral EMPD involving the buccal mucosa and gingiva of an 81-year-old male with no known underlying internal malignancy. The Paget cells were positive for CK7, CK20, CAM5.2, and androgen receptor, but negative for SOX10 and p63. The immunophenotype, association with internal malignancies, and treatment approaches for oral EMPD are reviewed.

Male breast cancer represents only 1% of all breast malignancies, with ectopic breast cancer in men being even rarer and highly prone to diagnostic challenges. Extramammary Paget's disease (EMPD), a rare cutaneous tumor with non-specific clinical symptoms, is susceptible to misdiagnosis. This report discusses the case of an older male patient who presented with a scrotal mass, later identified as ectopic breast invasive adenocarcinoma upon pathological examination post-lesion excision.

Early detection and comprehensive diagnostic approaches for breast cancer are essential for improving prognosis. When it comes to changes in the skin of the breast or the nipple-areola complex (NAC), particularly if they are unilateral, it is essential to be vigilant, as these changes could be an early sign of underlying malignancy or other pathologies. Primary breast malignancies, such as mammary Paget's disease (MPD), can manifest as erythema, scaling, or ulceration of the NAC, while secondary cutaneous metastases from other breast carcinomas may present as nodules, erythematous plaques, or inflammatory reactions.

In a 2015 study of mutation carriers who had initial negative bone scintigraphy, we found that the rate of development of Paget's disease of bone (PDB) over 5 yr was low. We report here an additional 8-yr follow-up of this cohort, exploring the hypothesis that the rate of development of PDB would increase as the cohort aged. In the current study, 21 of 24 subjects from 2015 who had a negative bone scintiscan at baseline and at first follow-up, had a repeat scintiscan and measurement of total serum alkaline phosphatase activity.
