Background: Reconstruction surgery for skin and soft tissue defects of the penis would ideally secure sufficient volume, be safe in procedure, and involve a simple surgical technique. Among the wide variety of techniques that have been employed, the groin flap-based technique is considered a relatively simple option for volumetric reconstruction. In this retrospective study, the authors report cases of penile reconstructive surgery using a groin flap.Methods: We performed a retrospective chart review of patients with penile defects treated in our department. Reconstructive surgeries were carried out using pedicled groin flaps. Charts were reviewed to investigate duration of the surgeries, recovery and follow-up periods, and bulkiness at one and 10 months after surgery. Patients were observed postoperatively for complications, urination, and erectile function.Results: Six patients hospitalized from March 2009 to September 2013 for penile defects underwent surgery in our department. All patients recovered without any flap loss. The most common complication after surgery was wound dehiscence. Circumferences of penile shafts were measured at 1 and 10 months after surgery, and penile bulkiness at rest were found to be maintained at >86%. There were no patients with contracture, and in all patients, urination and erectile functions were satisfactory.Conclusion: Reconstructing penile defects using groin flaps was found to be favorable in terms of volumetric reconstruction and postoperative patient satisfaction. Furthermore, the surgery and recovery periods are short, and rates of complication and donor site morbidity are also low.

Necrotizing fasciitis is an infection of the subcutaneous tissue that results in destruction of the fascia and is disproportionately common in patients with chronic liver disease or diabetes. Necrotizing fasciitis of the head and neck is rare, but has a high fatality rate. A 50-year-old man with a past medical history of diabetes reported a chief complaint of a wound in the posterior neck due to trauma. The wound had grown and was accompanied by pus and redness, and the patient had a fever. When the patient was referred to department of plastic & reconstructive surgery, the sternocleidomastoid muscle, semispinalis capitis muscle, splenius capitis muscle, and trapezius muscles were exposed, and the size of the defect was about 25×20 cm. Dead tissue resection was performed before negative-pressure wound therapy, followed by a split-thickness skin graft (STSG). After a 2-week course of aseptic dressing post-STSG, the patient recovered completely. No postoperative complications were observed for 1 year. Necrotizing fasciitis is a life-threatening, rapidly spreading infection, requiring early diagnosis and active surgical treatment. In addition, broad-spectrum antibiotics are required due to the variety of types of causative bacteria. Broad necrotizing fasciitis of the posterior neck is rare, but can quickly progress into a life-threatening stage.

BackgroundLiposuction has become one of the most frequently performed procedures in the field of aesthetic surgery. Fat embolism syndrome after liposuction can easily be overlooked or underestimated; however, occasionally, fulminating fat embolism syndrome can develop and lead to a critical situation within 2–3 days after lipoplasty. Changes over time in the amount of circulating fat particles and the histology of major organs have not yet been studied.MethodsThis study was conducted using 18 male Sprague-Dawley rats aged 12 weeks and weighing 500–628 g (average, 562 g). Fifteen rats were used as the experimental group and 3 as the control group. Under general anesthesia, tumescent-technique liposuction was performed at the lateral flank areas and abdomen for 1 hour. Blood, lung, and brain tissue specimens were obtained at 1 hour, 1 day, and 2 days after the liposuction procedure.ResultsThe average number of fat particles in the blood samples was 25,960/dL at 1 hour, 111,100/dL at 24 hours, and 21,780/dL at 48 hours. The differences between study groups were statistically significant. Both intravascular and extravascular fat particles with inflammation were seen in all 15 rats, as were inflammatory cell infiltration, hemorrhage, and consolidation with shrinkage of the lung alveoli.ConclusionsThese results imply that there is a strong possibility of fat embolism syndrome after liposuction in real clinical practice, and the first 24–48 hours after the operation were found to be the most important period for preventing pulmonary embolism and progression to fulminating fat embolism syndrome.

A solitary fibrous tumor is a relatively uncommon neoplasm that usually occurs in the pleura but occurs extremely rarely in the oral cavity. Reported herein is a rare case of a solitary fibrous tumor in the buccal cheek mucosa. A 50-year-old man visited the authors' hospital due to a buccal cheek mass whose size had increased. Excisional biopsy was done under local anesthesia. After the excisional biopsy, the patient was diagnosed to have a solitary fibrous tumor. In immunohistochemistry, the patient's solitary fibrous tumor was characterized by the expression of CD34 and CD99 on the neoplastic cells, and negativity for Bcl-2 and S-100. No recurrence or complication occurred for a period of 5 years. The growth of a primary solitary fibrous tumor in the buccal cheek mucosa is extremely rare and has been rarely reported in the South Korean medical literature. A solitary fibrous tumor must be distinguished from other spindle cell tumors. Presented herein is a case of primary solitary fibrous tumor in the buccal cheek mucosa. The relevant literature is briefly reviewed.

Follicular occlusion triad (FOT) is a complex chronic inflammatory skin disease comprising hidradenitis suppurativa (HS), acne conglobata (AC), and dissecting cellulitis of the scalp (DCS; Hoffman’s disease or perifolliculitis capitis abscedens et suffodiens). While pathological mechanisms are responsible for common skin manifestations, the exact underlying causes of follicular occlusion have not yet been clearly identified. Therefore, the diagnosis and treatment of FOT remain challenging. A 31-year-old man on conservative treatment for previously diagnosed HS and AC presented to our clinic with multiple masses on his posterior neck and face. Excisional biopsy of the masses revealed epidermal cysts. Four months after the surgery, he presented with a painful palpable mass around the occipital region of the scalp with characteristic skin manifestations such as cicatricial alopecia and comedones and was diagnosed with DCS. Incision and drainage of the lesion were performed, and histopathology revealed pathological findings of follicular occlusion. The patient was diagnosed with FOT. Following the procedure, the patient has been on regular follow-up and is on oral isotretinoin; there have been no complications for the last 6 months.
