Terbinafine is now widely used for the treatment of dermatophytic infections of the skin and nails. Cutaneous side effects of terbinafine are rare and mild. They includes erythema, pruritus, urticaria, desqumation, and macular exanthem. In addition, fixed drug eruption, erythema multiforme, Stevens-Johnson syndrome, and erythema annulare centrifugum-like psoriatic drug eruption were recently described in the literatures. Herein, we reported a case of acute generalized exanthematous pustulosis induced by terbinafine.

Subepidermal calcified nodule, a form of idiopathic calcinosis cutis, typically present as a hard, 3 to 11 mm, solitary lesion on the exposed area of the head and the extremities. Here we re-port an unusual case of subepidermal calcified nodule occurring on the buttock. A 15-year-old girl presented with a 6-month history of a 12 × 6 mm, oval, hard, erythematous nodule on the right buttock. Histopathologic examination of an excision biopsy specimen revealed extensive deposition of calcium in the whole dermis as large multilobulated masses.

Acrokeratoelastoidosis of Costa is a rare palmoplantar keratoderma with autosomal dominant inheritance. It is clinically charaeterized by small, firm, yellowish, shiny, translucent papules occumng over the dorsal hands, the knuckles, and the lateral margine of the palms and soles. Histologically, the characteristic features are hyperkeratosis, aeanthosis, and most strikingly, fragmentation of coarse elastic fibers within the dermis. The lesions usually begin in early childhood and progress slowly. We herein report two familial cases of acrokeratoelastoidosis of Costa showing typical clinic1 and histopathological features.

Tegafur is a fluoropyrimidine structurally similar to 5-fluorouracil, used in the treatment of advanced gastrointestinal neoplasms. Mucocutaneous side reactions induced by this agent are rare and include photosensitivity of lichenoid and eczematous types, acral erythema, hyperpigmentation and palmoplantar keratoderma. However, to our knowledge, there has been no report of concurrent development of eruptions of two types in a patient. We describe a female patient with breast cancer, presented with combined features of acral erythema and hyperpigmentation due to oral tegafur.

Anetoderma is loose and wrinkled skin lesions that show the characteristic histopathological feature of focal loss of elastic fibers in the dermis. The primary type of anetoderma arises in clinically normal skin and the secondary type replaces the lesions of associated disorders including various infections, infiammatory diseases and tumors. However, anetoderma due to pilomatricoma is very rare. Our patient, a 21-year-old female, presented with a soft and wrinkled skin overlying a firm, pedunculated tumor on her left upper arm. The histopathological examination showed anetodermic cutaneous changes which were associated with the underlying pilomatricoma.

This study aimed to evaluate the perception of nutrition teachers about emergency meals in all schools affiliated with the Seoul Office of Education. The purpose of this study was to suggest the need for emergency meals and provide directions for future development, thereby assisting meal service sites. An online survey was conducted from May 26 to 31, 2021, analyzing 130 collected samples. The summary of the results is as follows: First, the nutrition teachers recognized the need for school meal services for the prevention of the spread of infectious diseases and considered the variance among school meal consumers. Also, they generally thought of emergency meals due to the need for social distancing and the decrease in the distribution of food. Secondly, in terms of the differences in the perception about emergency meals, nutrition teachers (45.4%) who have provided emergency meals (t=2.584, P＜0.05) were more aware of the need for emergency meals than nutrition teachers (54.6%) who had not provided emergency meals. Nutrition teachers conceived emergency meals to minimize the contact between people (45.6%) and to rectify the imbalance in nutrition (37.5). Next, emergency meal attributes were observed to be ranked in the order of convenience (3.49), safety (3.15), and satisfaction (2.88). Fourthly, although there were no meaningful differences in emergency meal attributes, there were statistically significant differences in the safety of the cooking process, menu familiarity, the low unit price compared to regular meals and the excellent satisfaction with nutrition provided (t=2.603, P＜0.05), (t=2.039, P＜0.05), (t=2.154, P＜0.05), (t=2.477, P＜0.05) respectively.

Coumarin-induced skin necrosis is a rare complication of oral administration of coumarin derivatives. Clinically, the lesions begin with well-defined purpuric patches and progress to bullae and necrosis on the trunk, buttock or female breast. Histopathologic findings show a fibrinoid degeneration or thrombus formation in the dermal blood vessels with occasional vessel rupture and hemorrhage. We report a 77-year-old man who suffered from a typical necrotic patch on his right buttock developing during the course of coumarin therapy. Our case was diagnosed as coumarin-induced skin necrosis, based on the characteristic clinical course and histopathologic findings.

Linear IgA bullous dermatosis (LABD) is an autoimmune subepidermal blistering disease characterized on direct immunofluorescence of perilesional skin by the linear deposition of IgA at the basement membrane zone. The pathogenesis of LABD is not known, but rar ely some cases of LABD have been reported in association with drug exposure. We report a case of drug-induced LABD showing linear deposits of IgA and IgG at the basement membrane zone on direct immunofluorescence of perilesional skin as well as typical clinical and histologic characteristics, although the causative agent could not be specified.

Traumatic fat necrosis is a localized reaction of panniculus resulting from blunt trauma occurring predominantly on large pendulous breasts in elderly females and on the face in children. The facial lesions in children need no treatment and therapeutic excision is not indicated because a reasonable cosmetic result comes from spontaneous healing in a year or more. The clinicians unfamiliar with this problem may have confusion in diagnosis and management. Herein we report a case of a three-year-old girl who presented with a 3 cm sized erythematous and bullous plaque on her right cheek. The diagnosis of traumatic fat necrosis was made following clinical and pathological findings.

We describe a case of cutaneous metastatic carcinoma with an unusual manifestation in a patient with lung cancer. A 71-year-old woman with adenocarcinoma of the lung presented with multiple grouped erythematous or light brown colored papules and nodules which had developed on the right lateral lower chest and upper abdomen along T6 dermatome for 4 months. Histopathological examination of a nodular lesion revealed moderately differentiated or well-formed, mucin-secreting glandular structures in the dermis, which were typical of cutaneous metastatic adenocarcinoma. This case represent an unusual case of zosteriform cutaneous metastatic adenocarcinoma.
