BACKGROUND: Extramammary Paget's disease (EMPD) is a rare malignant disease originating from the apocrine glands involving the perineum, vulva, axilla, scrotum, and penis.
OBJECTIVE: To study the clinical presentation, extent of disease, efficacy of treatment, and survival outcomes of the cases in a single institution.
METHODS: Retrospective observation data analysis of 19 EMPD cases was performed. Demographic information, clinical management records, and histopathologic data of individual cases were obtained from the inpatient hospital data registry.
RESULTS: The mean age (years) at time of diagnosis was 62.4 with equal gender distribution. Synchronous tumors were detected in 6 cases (31.5%). 18 out of 19 patients underwent definitive surgical management in the form of wide local excision (WLE) and reconstructive surgery. Positive margins were found in 11 (68.8%) cases and 7 out of these 11 cases underwent second look surgical intervention to achieve oncological clearance or adjuvant oncology treatment. Follow-up period for living patients varied depending on time of diagnosis and definitive treatment. 10 out 19 cases (52.7%) were alive at the time of the study. Among the 7 cases of mortality from cancer, 5 cases died from progression of underlying associated malignancy and only 2 cases died with advanced stage of EMPD.
CONCLUSION: EMPD can be quite aggressive, especially in the secondary form, and surgical management is challenging with a high rate of residual tumor at the surgical margin. EMPD can easily mislead the clinician and patient, leading to unnecessary delay prior to definitive effective management.
