Syringomatous adenoma of the nipple (SAN) is known to be a rare benign breast neoplasm. With a few cases documented in the literature, preoperatively diagnosing this tumor is a challenge, which often leads to invasive procedure such as mass excision with nipple removal. This study was aimed at presenting a case report of SAN and to conduct a review of published cases. Literature search was conducted through PubMed databases. Articles published from year 1983 to March of 2022 were included. Only histologically confirmed cases of SAN were included. The review was performed according to the PRISMA guidelines. Twenty-eight cases, How to cite this article: Park SK, Samat SH, Whitelock CM, Fortes T. Syringomatous adenoma of the nipple: A case series and systematic review.

The superior gluteal artery perforator (SGAP) flap can be challenging and in common with all flaps can develop venous and arterial insufficiency. Several prior studies have demonstrated the successful utility of hyperbaric oxygen therapy (HBOT) in the salvage of compromised flaps, mainly with deep inferior epigastric perforator, latissimus dorsi or transverse rectus abdominis myocutaneous flaps. SGAP flaps are autologous alternatives to abdominal-based flaps and provides adequate adipose tissue for breast reconstruction. We report a case of a woman in her 50s who underwent a delayed bilateral breast reconstruction using SGAP free flaps. Postoperatively, venous congestion of her right breast flap was noted for which she was referred for HBOT. An acceptable aesthetic result was achieved following 17 HBOT treatments. This is the first case we can find in the published literature of ischaemic SGAP free flap being salvaged by HBOT.
