Removal of an intraosseous hemangioma of the frontal bone through an anterior hairline incision: a case report

An intraosseous hemangioma of the frontal bone is typically removed via a coronal incision. This procedure, while effective, can be lengthy and may result in complications such as a prominent scar and hair loss. An alternative approach involves a direct incision in the forehead, which leaves a less noticeable scar and allows a quicker recovery. However, in this specific case, the patient declined both coronal surgery and surgery through a direct forehead incision due to cosmetic concerns. Therefore, we proposed an anterior hairline incision. A 35-year-old woman presented with a firm, non-mobile, palpable mass on her right forehead. Preoperative non-contrast computed tomography revealed a heterogeneous osteolytic lesion. We performed an excisional biopsy through the anterior hairline. Postoperative non-contrast computed tomography was conducted 2 and 6 months after surgery. The wound was clean and free of complications, and there was no local recurrence. Partial resection can reduce scarring for patients who are concerned about cosmetic outcomes. However, the potential for recurrence remains a significant concern. We present this case of an anterior hairline incision for a hemangioma located in the forehead, evaluated using serial computed tomography for both preoperative and postoperative imaging.

Rabbit model for the study of nasal tip plasty: a comparative cephalometric analysis after rhinoplasty

Background@#Open rhinoplasty and septoplasty have emerged as popular surgical techniques for both functional and aesthetic procedures. To study open rhinoplasty with or without septoplasty, the use of animals is necessary. However, no reports have been published on radiologic methods for evaluating rhinoplasty or nasal tip plasty in animals using cephalometry. In this study, a validated model of open rhinoplasty and septoplasty was utilized in rabbits to establish radiographic guidelines for assessing the degree of tip plasty in these animals. @*Methods@#Eight adult New Zealand rabbits were used to establish an autologous septal extension graft (SEG) model. The rabbits underwent concurrent submucosal septal resection and open rhinoplasty. The SEG was implanted using nasal septal cartilage. To evaluate the results of nasal tip plasty, lateral-view X-ray images were obtained preoperatively, as well as 2 days, 2 months, and 12 months postoperatively. @*Results@#This open rhinoplasty rabbit model appears to be a practical tool for studying open rhinoplasty and tip plasty, demonstrating statistically significant results following SEG implantation. Furthermore, it is suitable for training purposes, specifically for the submucosal resection of septal cartilage. @*Conclusions@#This study presents a statistical analysis of the long-term (1-year) postoperative results of SEG implantation, using experimental procedures like those utilized in humans. Through a cephalometric comparison of rabbit noses, the effect of various SEG and tip plasty methods on the rabbit nose can be objectively measured.

Rapidly Progressive Myxoinflammatory Fibroblastic Sarcoma with Sudden Onset Treated by Wide Excision: A Case with an Atypical Clinical Course / 대한피부과학회지

Myxoinflammatory fibroblastic sarcoma (MIFS) is a rare neoplasm that is frequently located in the distal extremities. Emerging evidence suggests that MIFS can also affect the proximal limbs, trunk, and scalp, and aggressive clinical courses have been noted. We report a case of MIFS that occurred suddenly in the patient’s forearm and grew rapidly within 2 weeks. A level of Ki-67 was observed in the patient’s lesion, which constitutes a considerable finding compared with most MIFS cases. The patient underwent surgical tumor removal, and no evidence of recurrence was noted. We highlight this case in view of its sudden occurrence and rapid local progression, which contradicts the usual features of this disease, suggesting that this clinical course might be attributable to the high Ki-67 value.

A Case of Trichoadenoma / 대한피부과학회지

Trichoadenoma is a rare, benign, cutaneous tumor with differentiation towards the infundibular portion of the pilosebaceous canal. Clinically, it occurs as a solitary tumor, and most commonly on the face. Histologically, it is characterized by numerous horn cysts lined with squamous epithelium and solid tumor islands in the dermis. A 25-year-old female patient presented with a solitary 0.7x0.7cm sized, skin-colored, central, depressed papule on the right cheek, which had been present for 7 years. Histopathologic findings showed the characteristic features of trichoadenoma.

A Case of Dermatomyositis Associated with Nasopharyngeal Carcinoma / 대한피부과학회지

Dermatomyositis is an idiopathic inflammatory myopathy characterized by progressive symmetric proximal muscle weakness and typical cutaneous lesions. Recently the association of adult dermatomyositis and malignancy has generated much attention. A 56-year-old male presented with skin eruptions, proximal muscle weakness, and a neck mass on the right side. Diagnosis of dermatomyositis was established by clinical investigation, muscle enzyme study, electromyogram, and histological findings of the skin and muscle. A computerized tomography scan and histologic finding of right neck mass showed nasopharyngeal carcinoma. The patient was treated with chemotherapy and radiotherapy, and showed partial remission of nasopharyngeal carcinoma, with some improvement of the skin eruptions. But muscle weakness and myalgia were aggravated. He was then treated with systemic steroids (prednisolone) and azathioprine.

A Case of Infantile Myofibromatosis / 대한피부과학회지

Infantile myofibromatosis is the most common of the juvenile fibromatoses and an unusual mesenchymal disorder characterized by the proliferation of tumors in the skin, muscle, bone and viscera. There are two forms of the disease: solitary and multicentric. A benign course with spontaneous regression is seen in most patients, but poor prognosis can be associated with the multicentric form, in which visceral organs may be involved. It usually presents in early childhood. We report a case of infantile myofibromatosis arising in the left sole of a female new born. Physical examination showed a firm, red colored 2x4cm sized tumor. Histological examination revealed a spindle cell tumor in the dermis with fascicles of plump spindle cells with a whorled arrangement.

A Case of Allergic Contact Dermatitis Due to EMLA(R) / 대한피부과학회지

EMLA is a eutectic mixture of 2.5% lidocaine and 2.5% prilocaine for topical anesthesia and commonly used to avoid pain in cutaneous surgery or vascular punctures. We describe a 27-year-old female who had lower extremity hair removed by laser treatment after EMLA application and subsequently developed of adverse reactions, including itching, erythema and edema. Patch testing with EMLA showed allergy reaction at day2 and day4.

Quality of Life in Patients with Psoriasis / 대한피부과학회지

BACKGROUND: Quality of life is a broad concept that incorporates all aspects of an individual's existence. Psoriasis is a chronic relapsing disease of the skin and may produce a range of quality of life impacts, as complex as those from a more debilitating and life-threatening disease. However, the association between quality of life in psoriasis patients and their clinical characteristics has not yet been investigated in Korea. OBJECTIVE: The purpose of this study is to compare the quality of life in patients with psoriasis and healthy controls by using the WHO Quality of Life (QOL) Scale. This evaluates the domains of physical health, psychological health, social relationship and the environment, to assess the quality of life in patients with psoriasis by using the generic (WHOQOL) and dermatology-specific questionnaires (Skindex-29). The relationship between their quality of life and their clinical characteristics, comprising; onset, sex, age, education, duration of symptoms, severity, stress, anxiety and depression will be investigated. METHODS: Seventy one patients with psoriasis and twenty nine healthy controls were recruited in this study all of whom completed the WHOQOL Scale. The total scores and the scores of the domains of the WHOQOL Scale in both groups were compared. Correlation analysis and multiple regression analysis were performed to examine the relationship between quality of life and the clinical characteristics in patients with psoriasis. RESULTS: The total WHOQOL scores and all domain scores, except those of the environmental domain, of the WHOQOL scale in patients with psoriasis were lower than those of the healthy controls. scores for the Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI) and the Psoriasis Life Stress Inventory (PLSI) were all high. The high self reported severity, long duration, high PASI score and low education levels all showed significant correlation with low QOL. Of these characteristics, the BDI, BAI, PASI, and the self reported severity showed strong association with QOL. Stepwise multiple regression analysis revealed the BDI score, PLSI score, and education level were influencing factors on QOL scores. CONCLUSION: The quality of life in patients with psoriasis was poorer than that of the healthy controls. The association between QOL and the self reported severity was stronger than the QOL and the PASI score. The severity of depression and stress were the most important predictors on QOL

A Case of Generalized Pustular Psoriasis Associated with Myasthenia Gravis / 대한피부과학회지

Generalized pustular psoriasis(GPP) is an uncommon and severe form of psoriasis. The possible provocative factors such as steroid therapy, infection, stress, drugs, pregnancy, sun exposure, and metabolic disorders were reported. Among them, corticosteroid therapy is thought to be the most common factor. Although the cause of psoriasis remain obscure, the coexistence of psoriasis and autoimmune disease and cyclosporin accepted for the treament of psoriasis emphasize the importance of immunologic mechanism in the pathogenesis of psoriasis. We present a case of GPP in a 48-year-old male, who has had a history of myasthenia gravis since the age of 34 years and managed with long-term corticosteroid therapy. With the administration of acitretin and cyclosporin, generalized pustular eruptions nearly cleared and clinical improvement was achieved.

A Case of Deep Juvenile Xanthogranuloma / 대한피부과학회지

Juvenile xanthogranuloma(JXG) is a disorder of histiocytes usually associated with cutaneous lesions. JXG developing in soft tissue is rare and receives little attention. Therefore deeply located JXG may present a diagnostic difficulty in the absence of cutaneous lesions. Clinically, deep JXG seems to occur as solitary lesions on the trunk rather than on the head and neck region and tends to be composed of a monotonous population of histiocytic cells, with rare, if any, foamy macrophages or Touton-type multinucleated giant cells. We report an unusual case of JXG in a 4-month-old male infant who had a deep-seated mass located on the subcutaneous and muscle layer of the left forearm.
