Dermatofibrosarcoma Protuberans is a rare mesenchymal tumor, highly infiltrative and with a high recurrence rate. Despite its localization may vary, the trunk is widely recognized as the most common interested site. We read with interest the recent article published by Longo et al. "Recurrent dermatofibrosarcoma protuberans of the clavicular region: radical excision and reconstruction with Latissimus Dorsi myocutaneous flap"; since their case is very similar to one we faced in 2016. In this letter, we present our experience with the Thoraco-acromial artery perforator flap (TAAP) for reconstruction of a recurrent DFSP of the clavicular region.

Background Basal cell carcinoma is the most common non-melanoma skin cancer of the nose. Defects of the nasal ala and tip region are among the most difficult to repair due to their intrinsic characteristics. Objective To present our experience with the extended rotation flap for reconstruction of nasal ala defects and evaluate the outcome using the Patient and Observer Scar Assessment Scale (POSAS). Methods and Materials Twenty-two patients with partial thickness nasal ala defects reconstructed using the extended rotation flap were assessed. Final cosmetic and functional outcomes were evaluated using the POSAS. Results Flaps survived in all the reported cases and no major complication was recorded. Histology showed complete excision of the tumour in all cases. Using the POSAS, the mean overall evaluation for patients was 1.8/10, while the mean overall evaluation for the evaluation panel was 2.2/ 10. Conclusion Although similar flaps have been previously described, the extended rotation flap for nasal ala and tip reconstruction represents a functionally and cosmetically appealing wound closure option, respecting and avoiding any distortion of the alar crease.

MR and 18F-FDG PET/MR images of a 15-year-old boy with recurrent mild abdominal pain and hyperamylasemia demonstrating a pancreatic head lesion hypointense on the T1-weighted and slightly hyperintense on the T2-weighted images, with very small pseudocystic areas, restricted diffusion on the apparent diffusion coefficient map, and focal FDG uptake. No other pathologic findings such as enlarged lymph nodes, vascular invasion, metastases, dilatation of the main pancreatic duct, or pathologic uptake of the parotid glands were detected. The MR features, even if atypical, together with the focal uptake, allowed the diagnosis of pediatric solid pseudopapillary pancreatic tumor, which was then confirmed by histology.
