Background: A large number of patients suffer from deliberate self-harm scars. In recent years, there have been reports of resurfacing with skin grafts, but there are no large-scale reports.
 Method: Eighty patients underwent resurfacing with a rotated skin graft. Tumescent local anesthesia (TLA) was administered. The skin at the scar site was cut with an electric dermatome to a thickness of 8/1,000 inches and then rotated 90° and transplanted. Patient and observer scar assessment scale (POSAS) and a questionnaire (1 point = satisfied, 10 points = dissatisfied) were used to evaluate scarring and the patient's worries about improvement at one year after the operation.
 Results: The average overall evaluation in the POSAS was 2.7 points; thus, the postoperative scarring was evaluated to be satisfactory. Furthermore, the patients' preoperative worries about improvement after the operation was also evaluated to have improved postoperatively with an average of 3.5 points.
 Conclusion: Resurfacing deliberate self-harm scars with a rotated skin graft is a highly useful surgery that can be performed under local anesthesia as day surgery without any complications.

 We treated two cases of severe bleeding due to an acquired coagulation factor XIII deficiency. The first case was a 69-year-old man. With the assistance of our orthopedic surgeon, we performed multiple operations for rhabdomyolysis resulting from lower leg compartment syndrome, including excision of the soleus muscle. The second case was an 82-year-old man with sacral pressure ulcers that we treated by debridement and flap plasty. After the operations, laboratory data revealed no abnormal coagulation or thrombocytopenia; however, uncontrolled, severe bleeding occurred despite frequent blood transfusions. Following a hematology consultation, it was determined that the patients had a severe coagulation factor XIII deficiency due to surgical bleeding. Subsequently, the bleeding stopped after the administration of blood coagulation factor XIII concentrate. We report these uncommon cases along with a review of the literature.

 In 2018, Marek classified lipoma as intraneural lipoma, extraneural lipoma, and lipomatosis of nerve based on the positional relationship between the epineurium and lipoma. Furthermore, he proposed a hybrid type, with combined characteristics of these pathologies. Herein, we describe a hybrid-type lipoma with a radial nerve running inside the tumor. The patient was a 67-year-old female who visited our hospital with a chief complaint of a tumor in her left arm. MRI indicated the radial nerve was running inside the tumor. Although we preserved the nerve during resection of the tumor, postoperative radial nerve palsy, including drop hand and hyperesthesia symptoms, was observed. The wrist drop improved 7 months after surgery, and hyperesthesia improved after 9 months. Hybrid-type lipoma is a rare condition; to our knowledge, only nine cases have been reported. Because it is difficult to separate the nerve from the hybrid-type lipoma during resection, careful dissection under a microscope is desirable.

 Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue tumor with intermediate malignant potential. We present a 5-year-old boy with AFH mimicking a hemangioma. He had a slowly growing subcutaneous tumor on his upper arm for 2 years. Ultrasonography showed the tumor had a rich blood flow, and hemangioma was suspected. The patient had no systemic symptoms, but blood tests showed elevated inflammatory responses and increased levels of interleukin-6, vascular endothelial growth factor, and immunoglobulins. Castleman disease was suspected, and the tumor was resected. Pathological examination revealed the presence of the EWSR1-CREB1 fusion gene. He was diagnosed with AFH. Hyperinflammation improved rapidly after tumor resection. AFH is a soft tissue tumor with few metastases and low mortality; however, it is often misdiagnosed and there is no established cure. Our findings suggest a diagnosis of AFH should be considered in cases of blood flow-rich subcutaneous masses with hypercytokinemia.

 Angioleiomyoma is a rare benign but painful tumor that usually affects the lower extremities in women. Angioleiomyoma of the face is extremely rare and is usually painless. We report a rare case of an angioleiomyoma of the forehead in a 56-year-old man. This tumor is histopathologically classified into capillary, venous, and cavernous types. Pain experienced in the capillary type of angioleiomyoma is attributable to sympathetic nerve ischemia; however, recent studies suggest sensory nerve involvement as well. The exact pathophysiology and etiological basis of pain remain unclear. Further research, including greater details of histopathological findings, is warranted to gain deeper insight into this lesion.

 Myasthenia gravis causes ptosis in some patients. Medical treatment is preferred over aggressive surgery in these patients. We report a case of ptosis surgery, which was performed using the frontalis sling technique, in a patient who developed this ocular complication during a steroid taper. Ptosis surgery was effective and reduced the dose of medication and minimized the adverse effects of steroids. The patient's symptoms remained stable for 32 months postoperatively.

 We present a case of malignant lymphoma with onset in the canine fossa, with suborbital neuropathy as the initial symptom. The head and neck region is a frequent site of onset for malignant lymphoma, which sometimes appears as an orbital space-occupying lesion, leading to a diagnosis of orbital apex syndrome or with oculomotor nerve palsy as the initial sign. There have been few reports of malignant lymphomas with suborbital neuropathy as the presenting symptom. In the present case, the only preoperative symptoms were subcutaneous buccal tumor and sensory abnormality in the region supplied by the suborbital nerve; hence, suborbital schwannoma was initially suspected. Diagnosis was difficult. We report this case with a discussion of previously published reports.
