Case Reports
Laparoscopic pancreaticoduodenectomy for metastatic pancreatic melanoma: A case report.
Pancreatic metastases from other malignant tumors are an uncommon clinical condition and account for approximately 2% of all pancreatic malignancies. The most common primary malignancy that metastasizes to pancreas is renal cell cancer. We reported a rare clinical case of metastatic melanoma to pancreas who underwent a successful laparoscopic pancreaticoduodenectomy (LPD) at our department. ⋯ Metastatic pancreatic tumors are often associated with well-defined margins, tumor necrosis, enhancement, and distant metastases without pancreatic duct dilatation and parenchymal atrophy. As the most common type of metastatic pancreatic tumor, renal cell cancers tend to have higher attenuation values than that of primary pancreatic cancer, while they had similar attenuation values on the portal phase. Primary pancreatic cancer was always associated with an elevated CA199, total bilirubin, and fasting plasma glucose levels. Surgical resection for metastases to pancreas should be aggressively considered in selected patients due to its unique value of providing palliation and a chance to cure. For patients with unresectable lesions, new therapeutic protocols should be recommended such as the combination of BRAF with MEK inhibitor and PD-1 blocker with or without ipilimumab.

Case Reports
An incidental diagnosis of a giant paraovarian cyst in a female teenager: A case report.
Paraovarian cysts (PCs) are cystic tumors that can be encountered between the ovarian hilum and the ovarian fimbria located within the mesosalpinx and broad ligament, being usually diagnosed within the 3rd and 4th decade of life. ⋯ In addition to their rarity, giant PCs can be an incidental diagnosis in patients presenting unrelated symptoms resulting in increased difficulties related to the diagnosis. Moreover, the imagistic tools might not establish precisely the origin of these cysts, and therefore, the final diagnosis and treatment approach could be determined sometimes only during the surgical intervention.

The effects of therapy on constricted ears are evaluated subjectively and objectively. However, previous methods are not specific, comprehensive, precise, or effective in diagnosing and predicting surgical outcomes. This study aimed to present a personalized, subjective evaluation scale and new objective indices utilizing a digital method for the accurate evaluation of constricted ears. ⋯ The specialized subjective scale reported in this study allows comprehensive and personalized assessment of constricted ears. The new objective indices are more effective than existing methods and the digital measurement method is precise and reliable. These methods will allow the treatment of constricted ears to be better evaluated, leading to improvements in patient management and treatment selection.

Observational Study
Reconstruction of complex nail matrix defect using the homodigital reverse fasciocutaneous flap.
Reconstruction of complex and severe nail matrix defects with the exposure of bone, tendon or joint continues to be challenging for the surgeon. We present our experience using the homodigital reverse laterodorsal fasciocutaneous flap in the reconstruction of complex nail matrix defects. Six patients (7 fingers) of complex nail matrix defects with the exposure of bone, tendon or joint were treated with the homodigital reverse laterodorsal fasciocutaneous flap based on the dorsal branches of the proper digital artery. ⋯ The mean size of the flaps was 1.4 × 2.4 cm (range, 1.2 × 2.0-1.5 × 3.0 cm); the mean follow-up period was 8 months (range, 4-15 months); patients' average time to get back to their former jobs was 4.3 weeks (range, 3-6 weeks) postoperatively. All patients were satisfied with the appearance and functional outcomes of the fingers. The homodigital reverse laterodorsal fasciocutaneous flap based on the dorsal branches of the proper digital artery is an ideal surgical method to reconstruct the complex and severe nail matrix defect.

Desmoid fibromatosis is a rare benign neoplasm arising from musculoaponeurotic structures with the potential to infiltrate local tissues and recur locally. While the commonly affected regions are the shoulder, chest wall and back, thigh, head and neck, localization in the foot is rare and only a few cases have been reported. Deep-seated lesions of foot tend to spread along the fascia and nerve or tendon sheaths. ⋯ Surgical excision is recommended for symptomatic lesions located in the foot. However, it is difficult to excise thoroughly and periodic follow-up is needed to monitor for recurrence. Further study is warranted to determine whether patients benefit more from function preservation instead of complete resection.
