Reconstruction for axillary hidradenitis suppurativa using one‐stage local tissue rearrangement: A retrospective analysis of 53 cases

Wide local excision offers a potential cure for severe axillary hidradenitis suppurativa. However, the gold standard for reconstruction has yet to be defined. Here, we describe our rotation advancement flap technique, which allows for one‐stage closure of large axillary defects, with minimal functional morbidity to the axilla. We performed a retrospective review of all patients who underwent one‐stage surgical management for axillary hidradenitis suppurativa at a single‐centre tertiary care hospital from 2009 to 2018. We identified 34 patients, with a total of 53 operative sites. The majority were female (85%) with a mean age of 31 years and body mass index 35 kg/m². The median defect size was 84 cm² and the majority were treated using the rotation advancement flap technique (86%). A quarter of operative sites experienced minor complications with only one requiring re‐operation. At a median follow‐up of 32 months, two (4%) sites showed decreased range of motion. However, all patients had achieved remission without any further recurrence of disease. We describe a one‐stage rotation advancement flap technique for management of moderate to severe hidradenitis suppurativa that achieves a high local cure rate, minimal functional morbidity, and acceptable wound complication rates.     

Evaluating the preoperative breast cancer characteristics affecting the accuracy of axillary ultrasound staging

We evaluate the preoperative breast cancer (BC) characteristics that affect the diagnostic accuracy of axillary ultrasound (US) and determine the reliability of US in the different subgroups of BC patients. Axillary US assessments in women with invasive BC diagnosed between 2009 and 2016 in a single institution were retrospectively reviewed. The diagnostic accuracy of axillary US was obtained using surgical nodal histology as the gold standard. Preoperative breast tumor sonographic and histological factors affecting axillary US diagnostic accuracy were examined. Of the 605 newly diagnosed invasive BC cases reviewed, 251 (41.5%) had nodal metastases. Axillary US sensitivity was 75.7%, specificity 92.9%, positive predictive value 88.4%, negative predictive value 84.4%, and false‐negative rate 24.3%. Lower US sensitivity was seen with invasive lobular cancer (ILC) (P = .043), grade I/II, (P = .021), unifocal (P = .039), and smaller tumors (P < .001). US specificity was lower in grade III (P < .001), estrogen receptor (ER)‐negative (P < .001), progesterone receptor (PR)‐negative (P = .004), HER2‐positive (P = .015), triple‐negative (P = .001), and larger breast tumors (P < .001). US has moderate sensitivity and good specificity in detecting metastatic axillary lymph nodes. Based on preoperative cancer characteristics, US was less sensitive for nodal metastases from ILC, unifocal, lower grade, and smaller breast tumors. It was also less specific in grade III, ER‐negative, PR‐negative, HER2‐positive, triple‐negative, and larger breast tumors. Caution is suggested in interpreting the US axillary findings of patients with these preoperative tumor features.     

Axillary Giant Lipoma: a Case Report

Lipoma are the most frequent mesenchymal soft tissue tumours but rarely present huge sizes in their cutaneous localization. Some cases of so-called “giant lipomas” have been reported in the literature and here is presented a giant lipoma of the axillary area which is, to our best knowledge, the second report of such a giant lipoma in this localization.     

Axillary basal cell carcinoma: additional 25 patients and considerations

Background Axillary basal cell carcinoma represents a rarely described occurrence in world literature. Objective To report our 14 years’ experience of axillary basal cell carcinomas. Methods A review of Pathology department database is given. Results Twenty‐five further patients with axillary basal cell carcinomas of 7367 basal cell carcinomas diagnosed are reported. These represent a percentage of 0.33%.The average age of patients was 64.96 years, not significantly different from the average age of patients with overall basal cell carcinomas. No patient had had previous radiant or immunosuppressive treatment or axillary sunburn. No patient had basal cell naevus syndrome. The subtypes involved were superficial and nodular. No patient of 17 patients followed up had recurrences or metastasis after 5 years of follow‐up. Conclusion Axillary Basal cell carcinomas are rare. No particular predisposing or risk factor is recorded. They do not seem to be significantly more aggressive than other basal cell carcinomas.
