Facial Pseudocyst Caused by Hyaluronic Acid Filler Injection: A Case Report / 대한피부과학회지

Administration of a hyaluronic acid (HA) filler injection is a common aesthetic procedure widely used for facial soft-tissue augmentation. Owing to their low immunogenicity, hyaluronic acid fillers have rarely been linked with serious long-term adverse effects. Although generally safe, reports of adverse events linked to hyaluronic acid filler injection are increasing following its extensive usage globally. We describe the case of a 33-year-old woman who presented with multiple facial nodules at sites of filler injection. To the best of our knowledge, this is the first reported case of facial pseudocyst related to monophasic hyaluronic acid filler injection, in Korea.

A Case of Wells' Syndrome Treated with Systemic PUVA / 대한피부과학회지

Wells' syndrome, or eosinophilic cellulitis, is characterized by recurrent cutaneous swellings which resemble acute bacterial cellulitis, and by distinctive histopathological changes. Skin lesions show dermal eosinophilic infiltration and the characteristic 'flame figures', but not pathognomonic, which are composed of eosinophil major protein deposited on collagen bundles. A 51-year-old woman developed a chronic, pruritic, erythematous to dark-brown colored, annular, infiltrated plaques with papules, vesicles and some crusts on the chest, abdomen, back and both forearms with the clinical and histological features of Wells' syndrome. Skin lesions had recurred frequently with systemic corticosteroids therapy, so we tried systemic PUVA and treated her successfully without recurrence until now.

A Case of Eosinoplilic Pustular Folliculitis / 대한피부과학회지

Eosinophilic pustular folliculitis (EPF) or Ofuji's disease is a cutaneous inflammatory follicular disorder of unknown etiology. It usually affects adults and is clinically characterized by recurrent crops of sterile and pruritic papulopustules grouped in an annular or polycyclic pattern involving preferably the seborrheic areas. Histopathologic examination reveals eosinophilic follicular abscesses. We report a case of eosinophilic pustular folliculitis in a 21-year-old man who showed pruritic erythematous plaques with follicular papules and pustules on the face, back, upper arms, and thigh. Laboratory test showed blood eosinophilia and histopathologic study revealed numerous eosinophilic infiltration in and around the hair follicle. The patient relatively responded well to dapsone and topical steroid.

A Case of Bullous Systemic Lupus Erythematosus:Clustered Tense Bullae Localized on the Face

A 21-year-old woman, who had a one-year history of pancytopenia with histiocytic necrotizing lymphadenitis and hepatosplenomegaly, presented with a 5 day history of tense bullae, which were localized on the face. These clusters of tense bullae occurred on clinically normal skin, she did not have other skin lesions. A diagnosis of bullous systemic lupus erythematosus (BSLE) was established based on clinical, laboratory, histological, and immunological findings. The bullae showed good responses to dapsone (100mg, daily) and resolved within 10 days with-out scaring. Bullous lesions of SLE may be the first cutaneous manifestation in some patients with SLE and should be considered in the differential diagnosis of the other subepidermal bullous disorders.

Perifolliculitis Capitis Abscedens et Suffodiens Successfully Treated with Isotretinoin / 대한피부과학회지

Perifolliculitis capitis abscedens et suffodiens is a rare chronic recalcitrant follicular disorder which clinically presents itself as pulstules, nodules, intercommunicating abscess and sinuses that leave atrophic, hypertrophic or keloidal scars. Although the etiology of this of condition is unknown, its association with acne conglobata and hidradenitis suppurativa, collectively termed the follicular occlusion triad, suggest a cammon basic pathogenic mechanism of follicular retention. The therapeutic problem is reflected in the variety of therapies that have been tried with varying degrees of success. We report a case of a 34-year-old man who showed a patch of alopecia on the vertex of his scalp. Clinically, the scalp showed multiple soft fluctuant elevated nodules with nonscarring alopecic patches. We performed a treatment with isotretinoin(13-cis-retinoic acid) during 6 months. The patients clinical appearance was much improved and local recurrence and hair loss have not been observed to date.

A Case of Benign Symmetric Lipomatosis / 대한피부과학회지

Benign symmetric lipomatosis is characterised by diffuse symmetric deposits of adipose tissue, predominantly on the neck, shoulder, back and upper extremities. We report a case of benign symmetric lipomatosis in a 61-year-old-man, which was first noted one year previously. It began growing rapidly about 3 months ago and was associated with alcoholic liver disease. Histopathological findings showed that the reticular dermis had been replaced by normal uncapsulated mature fat cells that were slightly increased in number in the fibrous connective tissue. He was treated with theophylline 300mg/day for two months.

Cutaneous Horn Arising from Keratoacanthoma / 대한피부과학회지

Cutaneous horn is a clinica) diagnosis based upon the presence of a large protuberant mass of keratin. We report a case of cutaneous horn arising from keratoacanthoma in a 76-year old woman. The patient showed a dome-shaped nodule 2n in diameter with a central crater on thc right temple area. A yellow brown colored cornical hyperkeratotic protruding lesion(0.7* 0.7cm size) from the central crater of the nodule was also observed. Histopathological findings of the lesions showed charaeteristic findings of keratoacanfhoma and cutaneous horn. The lesion was removed by surgical excision.
