A Clinical Study of Prevalence of Telogen Effluvium after Childbirth / 대한피부과학회지

BACKGROUND: Telogen effluvium (TE) is a form of nonscarring alopecia, characterized by diffuse scalp hair thinning in response to some form of physiologic stress. It is commonly described in women subsequent to childbirth. OBJECTIVE: The purpose of this study was to evaluate the prevalence of TE after childbirth. METHODS: Medical records from January 2006 to June 2007 of 240 postpartum patients from our obstetric department were reviewed. Telephone interviews with TE patients were conducted to investigate the initial occurrence time, restoration time, and treatment history. RESULTS: Prevalence of TE according to parity is higher in multiparas than primiparas (p=0.026). In addition, the prevalence of TE after a cesarean section delivery is higher than that after non-surgical delivery (p=0.014). Prevalence of TE with respect to weight gain is higher in the groups displaying agreater increase in weight (p=0.014). Finally, prevalence of TE according to gestational age is higher in groups giving birth after 38 weeks gestational age (p=0.015). CONCLUSION: Prevalence of telogen effluvium may be associated with multiparity, cesarean section, marked weight gain, and high gestational age.

A Case of Myxoid Liposarcoma / 대한피부과학회지

Liposarcomas are one of the most common soft-tissue sarcomas in adults. They usually arise in the deep soft tissues, and patients present with large painless masses. Four major types of liposarcomas are generally recognized and have epidemiologic and prognostic differences: atypical lipomatous neoplasm/well-differentiated; myxoid/round- cell; dedifferentiated; pleomorphic variants. Myxoid liposarcoma is the second most common type of liposarcoma, representing 30~40% of all liposarcomas in the extremities. We report a case of myxoid liposarcoma in a 78-year-old man who presented with an asymptomatic, firm, deep-seated mass in the lateral aspect of his left upper arm.

A Case of Juvenile Xanthogranuloma Developed in a Neurofibromatosis Child with Family History / 대한피부과학회지

Juvenile xanthogranuloma (JXG) is a fibrohistiocytic proliferative disorder predominant in infancy and childhood. It is a benign and transient skin lesion that usually appears in the cephalic area. Recently, the concurrent finding of neurofibromatosis (NF), juvenile chronic myelogenous leukemia (JCML), and JXG has been repeatedly reported. Especially, the family history of NF may represent a risk factor for the development of JCML in patients with NF and in patients with NF and JXG. So, a finding of JXG and NF in infants should alert the physician to a possible development of JCML. We report a case of JXG developed in a neurofibromatosis child with family history.

A Case of Post-traumatic Pyoderma Gangrenosum Associated with Ulcerative Colitis / 대한피부과학회지

Pyoderma gangrenosum is a painful, chronic, ulcerating skin disease associated with a wide variety of disorders, including Crohn's disease, ulcerative colitis, and Behcet's disease. Etiology of pyoderma gangrenosum is unknown but the lesions frequently appear at points of trauma and it is related with pathergy. We report a case of post-traumatic pyoderma gangrenosum occurring in ulcerative colitis with a review of the literature.

A Case of Jessner's Lymphocytic Infiltration / 대한피부과학회지

Jessner's lymphocytic infiltration of the skin (JLIS) is a well-known but poorly understood disorder. Some doubt still exists about whether it is a distinct disease or a variant of lupus erythematosus or, less commonly, polymorphous light eruption, cutaneous lymphoid hyperplasia. An effective therapy is still unavailable for JLIS. We report a patient with JLIS which was successfully treated with dapsone and intermittent systemic glucocorticoid therapy.

A Case of Lichenoid Drug Eruption with Whole Body and Oral Mucosal Involvement Caused by Antituberculosis Drugs / 대한피부과학회지

Lichenoid drug eruption can arise as a result of exogenous compound exoposures and closely mimic idiopathic lichen planus. A 45-year-old man who had taken antituberculosis drugs (isoniazid, rifampin, ethambutol, pyrazinamide) for 2 months developed pruritic violaceous papules and plaques with silvery scales on the whole body. On close inspection, he had superficial erosions on the lips and reticulate white papules on the buccal mucosa. Histopathologic findings were hyperkeratosis, parakeratosis, and hypergranulosis in the epidermis and band-like lymphohistiocytic infiltration, numerous eosinophils, and perivascular lymphohistiocytic infiltration in the dermis. The skin lesions improved leaving hyperpigmentation after cessation of the antituberculosis drugs and application of topical corticosteroid.
