Introduction The use of abdominal flaps is recognized as a very advantageous approach for breast reconstruction with gradual refinements leading from the pedicled transverse rectus abdominis musculocutaneous flap to the criterion standard deep inferior epigastric perforator (DIEP) flap and its several variations. A systematic review with meta-analysis attempts to investigate the safety of the bipedicled DIEP flap for unilateral breast reconstruction. Methods The literature search used “PubMed” database, and a relevant study conducted at the Queen Victoria Hospital was also included. The extraction of data included study type, follow-up, patients' age, body mass index, preexisting abdominal scars, timing of reconstruction, operating time, flap inset, pedicles' configuration, flap failure, revision, and complication rates. Proportions were pooled with Freeman-Tukey arcsine transformation, and meta-regression was performed to evaluate whether complication rates were modified by different variables. Results Fourteen eligible articles provided an overall sample of 486 flaps, with a median follow-up of 18.5 months. In most cases, immediate reconstruction with undivided flap was performed, with equal use of extraflap and intraflap pedicles' configuration. Only 4 cases of flap failure (0.82%) were documented, with 18% overall complications and 3% fat necrosis rate. The forest plot showed significant between-study heterogeneity, and meta-regression revealed marginal positive association between older patient and complication rate. Conclusions Bipedicled DIEP flap for unilateral breast reconstruction is a technique that maintains the complications rate relatively low in challenging postmastectomy cases. Further comparative studies are needed to substantiate the findings of this study.

Summary: Hibernoma is considered as a rare soft tissue benign tumor originating from brown fat. Few cases have been described so far in the literature; hibernoma was first described by Merkel in 1906, but it was named by Gery in 1914. We present the case of 33-year-old woman who presented with a palpable lump over superior aspect of her thigh associated with pain. Magnetic resonance imaging examination reported a “dumbbell”-shaped soft tissue tumor involving the right side of the pelvis and adductor compartment passing through the obturator foramen into the adductor compartment infiltrating the hip joint. Clinical and imaging features initially suggested liposarcoma, but ultrasound-guided biopsy and final surgical resection yielded the diagnosis of hibernoma. This rare soft tissue tumor can imitate malignancy, but magnetic resonance imaging and possibly guided biopsy are essential for preoperative planning as surgical resection remains the best management pathway.

Breast cancer in men is rare and only about 390 men in the UK are diagnosed with breast cancer each year with an incidence rate in the UK of 1.5 cases per 100 000 men. In addition, the increased use of radiotherapy for management of breast cancer has led to a reported increase of radiation induced angiosarcomas (RIAS) with an incidence of 0.05–0.3%. Here we report a unique and extremely rare case of RIAS of breast in a male patient. To our knowledge this is the only case in the literature of a radiation induced angiosarcoma of the breast in a male.
