Axillary Paget disease with a visible satellite: a case report and literature review.

BACKGROUND: Extramammary Paget disease (EMPD) is an uncommon malignancy affecting apocrine gland-bearing skin, such as vulvar, perianal, axillary and penoscrotal areas. Paget cells are sometimes detected outside clinical border in a phenomenon called subclinical extension. Satellite is one of the patterns of subclinical extension which is likely to be invisible. The standard management strategy for EMPD without distant metastasis is a complete surgical removal, sometimes called wide local excision. However, there is no consensus regarding surgical margin width to decrease the high recurrence rate. Here we describe the first macroscopically visible satellite of axillary EMPD and wide local excision of both main lesion and the satellite lesion with only 0.5 cm margin, succeeded by a short review of the literature. CASE PRESENTATION: A 48-year-old female with a red macule in the right axilla was presented to our clinic. A well-demarcated 4 cm × 3 cm erythematous plaque was observed in the right axilla, and a similar lesion measuring 0.5 cm × 0.3 cm was found 3.5 cm away from the primary site. Breast and axillary node examination was unremarkable. Biopsy of the large plaque revealed Paget disease, then we performed a local extended excision of both lesions with a 0.5 cm margin, all margins negative indicated, by frozen pathology. Pathology revealed the nature of the satellite beside the main lesion also as Paget disease. The patient is currently followed-up for 20 months and has shown no signs of recurrence, with normal shoulder motor function. CONCLUSION: We have report the first visible satellite of extramammary Paget disease, indicating the necessity of an extended local resection of both the main leision and the satellite lesion. Considering the anatomical structure of axillary Paget disease, a 0.5 cm negative surgical margin indicated by frozen pathology might be sufficient to sustain the shoulder motor function.

Use of the Ipsilateral Anteromedial Thigh Flap for Immediate Rescue of Nonviable Anterolateral Thigh Flaps in Head and Neck Cancer Reconstruction.

BACKGROUND: It is not always possible to use the anatomically variable free anterolateral thigh (ALT) flap for reconstructive surgery. An anteromedial thigh (AMT) flap serves as a good alternative, and shares the same vascular pedicle as the ALT flap. METHODS: Of 698 reconstructions performed in 2006 to 2013 following head and neck tumor ablation surgery, ALT flaps were used in 653 patients. Eighteen free AMT flaps were harvested to replace variant nonviable ALT flaps. RESULTS: The lack of a sizable perforator in the ALT flap territory was the main reason for changing the reconstruction plan. Anteromedial thigh flap size ranged from 10 × 4 to 30 × 8 cm. The flap survival rate was 100%. The follow-up period ranged from 3 to 56 months. CONCLUSION: During head and neck reconstruction, when no sizable perforator is available during harvest of the ALT flap, successful reconstruction can be achieved using the ipsilateral AMT flap without additional donor-site morbidity.
