Topical Tretinoin Treatment for Confluent and Reticulated Papillomatosis / 대한피부과학회지

BACKGROUND: Confluent and reticulated papillomatosis (CRP) is a rare cutaneous disorder, characterized by persistent, scaling brown papules, patches, and plaques located on the trunk, neck, axillae, and shoulders. Many different treatments with variable success have been attempted, and oral minocycline treatment is effective in most patients with CRP. There were a few case reports of CRP responding to topical retinoid, but no clinical studies on the efficacy of the topical retinoid treatment for CRP have been reported. OBJECTIVE: The purpose of this study was to evaluate the efficacy and safety of the topical tretinoin treatment for CRP. METHODS: A retrospective study was performed based on the medical records and clinical photographs of patients with CRP treated with 0.025% tretinoin cream. RESULTS: Nine patients (4 men and 5 women) were enrolled in the study. The mean age of the patients was 17.4 (11~34) years and the mean age at onset of CRP was 15.1 (3~33) years. The duration of disease varied from 1 month to 7 years. Six of the nine patients showed complete remission, and CRP lesions improved markedly after averagely 6.2 weeks from the beginning of the topical tretinoin treatment. The treatment response was better in patients without itch than in patients with itch (p=0.048). Adverse effects were detected in 3 patients, and were mild irritant contact dermatitis to the topical tretinoin. CONCLUSION: We think that topical 0.025% tretinoin treatment is an effective and safe treatment modality for CRP and this treatment can be an alternative or additional modality to the systemic treatment.

A Clinical Study of Herpes Zoster: Focused on the Characteristics of Pruritus in Herpes Zoster / 대한피부과학회지

BACKGROUND: Herpes zoster is a common dermatologic disorder. However, there have been no reported studies of the characteristics of pruritus in herpes zoster in Korean literature. OBJECTIVE: The purpose of this study is to investigate the epidemiological features and clinical characteristics of pruritus in herpes zoster. METHODS: Retrospective study was performed by reviewing the medical records of 178 patients with herpes zoster. The analyses of age, gender, accompanying symptoms, dermatomal distribution, underlying disease, treatment and complication were performed. RESULTS: The ratio of male to female patients was 2:3. The age distribution ranged from 1 to 87 years old. A total of 76.4% of the patients with herpes zoster experienced pruritus, and 18.4% of the patient with pruritus had pruritus that disrupted normal activities. There were no relationships between the incidence of pruritus and age of patients, gender, dermatomal distribution, and incidence of pain. As the severity of pain increased, the incidence and the severity of pruritus increased (p=0.01, p=0.01). Pruritus was improved within 3 weeks in the 74.3% of the patients with pruritus; however, 9.6% of the patients felt complaint with pruritus over 6 weeks. The duration of the pruritus extended with advancing age (p=0.01). As the severity of pruritus and pain increased, the duration of pruritus increased (p=0.025). CONCLUSION: Pruritus is a common symptom in herpes zoster, and this study describes the general aspects of pruritus in herpes zoster. Advancing age and the severity of the pruritus and the pain are possible risk factors of long-lasting pruritus.

Mycosis Fungoides with Coincidental Ureter Cancer / 대한피부과학회지

An 82-year-old woman presented with a 5-year history of erythematous to brown patches and plaques on both legs, arms and trunk. Histopathological findings of biopsy specimens were consistent with mycosis fungoides, and the tumor cells were positive for CD3 and negative for CD20 in immunohistochemical stain. Imaging studies proposed the suspicion of ureter cancer, and the result of cystoscopic biopsy showed papillary urothelial carcinoma. Mycosis fungoides is the most common type of cutaneous T-cell lymphoma, characterized by variable cutaneous manifestations, including patches, plaques, tumors, and erythroderma. There were several studies concerning the evaluation of the second malignancy risk after cutaneous T-cell lymphoma, however the relationship between mycosis fungoides and ureter cancer is not revealed. This patient is considered a case of mycosis fungoides with coincidental ureter cancer.

Atrophying Pityriasis Versicolor / 대한피부과학회지

Atrophying pityriasis versicolor is a rare variant of pityriasis versicolor. Clinically, atrophying pityriasis versicolor is characterized by well defined, slightly scaly, depressed macules and patches with minimal symptoms. The etiology of the atrophy is unknown, though several hypotheses have been suggested, including immune reaction to antigens of Malassezia species. A 23-year-old male was presented with multiple, slightly brown colored macules and patches on the chest and back. In the potassium hydroxide preparation, lots of yeasts and hyphae were found. A histopathologic study showed multiple yeasts and hyphae on the stratum corneum, focal epidermal thinning, and perivascular lymphocytic infiltration on the upper dermis. The patient was treated with 100 mg itraconazole a day with topical antifungal agents. After 3 weeks of treatment, clinical improvement and mycological improvement were achieved. We present an additional case of atrophying piryriasis versicolor developed on the chest and back with the review of the relevant literature.

A Case of Adenoid Cystic Carcinoma on the Nipple with Axillary Lymph Node Metastasis / 대한피부과학회지

Adenoid cystic carcinoma of the breast is an uncommon type of breast cancer, and it accounts for 0.1% of all breast cancer. In contrast to the aggressive nature of extramammary adenoid cystic carcinoma, adenoid cystic carcinoma of the breast has a more favorable prognosis. A 55-year-old female patient presented with a 6-month history of a tender mass confined to the nipple of the left breast. A skin biopsy showed a linear and tubular pattern of atypical cells, which was consistent with adenoid cystic carcinoma. Left breast conserving surgery with axillary lymph node dissection was performed. The histopathology of the specimen showed a 1.5 cm sized mass localized to the nipple, and the axillary lymph nodes were positive for tumor metastasis.

Lichen Planus Pigmentosus-inversus / 대한피부과학회지

Lichen planus pigmentosus (LPP) is a rare variant of lichen planus, and it is characterized by hyperpigmented, dark brown to violaceous colored macules or patches on the sun exposed areas of the skin. The term of LPP-inversus was proposed to describe some cases with LPP arising on the intertriginous areas. Clinically, LPP-inversus is characterized by well defined dark brown to violaceous macules or patches with minimal symptoms and it is predominantly confined on the flexural areas. The histological characteristics are a lichenoid inflammatory infiltrate on the upper dermis, melanophages and pigmentary incontinence. The clinical course can vary. We present here an additional case of LPP-inversus that developed on the both inguinal folds and we review the relevant literature.

Morphea Developing at the Site of Healed Herpes Zoster

Wolf's isotopic response describes the occurrence of a new, unrelated disease that appears at the same location as a previously healed skin disease, and the most common primary skin disease of this phenomenon is herpes zoster. Several cutaneous lesions have been described to occur at the site of healed herpes zoster, and granulomatous dermatitis and granuloma annulare have been reported to be the most common second diseases. The pathogenesis of the isotopic response is still unclear. Morphea can develop at the site of regressed herpes zoster and a few such cases have been reported. We present here an additional case of morphea that developed at the site of previously healed herpes zoster, and we review the relevant literature.

A Case of Blaschkitis / 대한피부과학회지

Blaschkitis is an acquired inflammatory dermatosis that develops along the line of Blaschko. It has a similar appearance to lichen striatus but, shows a somewhat different clinical course and histopathologic findings. Spongiotic dermatitis-like histopathology, good response to glucocorticoid therapy and frequent relapses are the characteristic features that can differentiate it from lichen striatus and other dermatoses which follows the line of Blaschko. We report a case of Blaschkitis that showed a typical clinical course and histopathologic findings.

A Case of Woringer-Kolopp Disease on the Leg / 대한피부과학회지

Woringer-Kolopp disease is a rare variant of mycosis fungoides and it is also known as localized pagetoid reticulosis. It presents as a solitary, localized hyperkeratotic patch or plaque on the extremities with a slowly progressive course. A 51-year-old female presented with a 6-year history of a well-defined erythematous plaque with an indurate border on the left leg. The lesion was asymptomatic and it had gradually enlarged. A skin biopsy showed hyperkeratosis and acanthotic epidermis with an infiltration of atypical pagetoid cells, and these cells were revealed to be the cytotoxic T cell phenotype on immunohistochemical staining. We report here on a case of Woringer-Kolopp disease along with a review of the relevant literature.

Kikuchi's Disease Presented with Cutaneous Lesion Showing Diffuse Erythematous Maculopatches / 대한피부과학회지

Kikuchi's disease, or histiocytic necrotizing lymphadenopathy is an idiopathic, benign self-limiting lymphadenitis usually affecting young women. Cutaneous findings in Kikuchi's disease have been reported in 16~40% of cases. A 29-year-old woman presented with pruritic diffuse erythematous maculopatches on whole body accompanied by long-lasting fever and cervical lymphadenopathy. Skin biopsy showed vacuolar degeneration of the basal layer and dermal infiltration of CD68-positive histiocytes. Lymph node fine needle aspiration specimens showed abundant lymphocytes, histiocytes, karyorrhectic debris without neutrophils, consistent with Kikuchi's disease. We present a case of Kikuchi's disease showing generalized skin eruption with a review of literature that describes patterns of skin involvement.

A Case of Palmar Lichen Nitidus Presenting as a Clinical Feature of Pompholyx

Lichen nitidus (LN) is an uncommon chronic eruption of an unknown cause, and it is characterized by tiny, discrete, flesh-colored papules. The sites of predilection are the genitalia, trunk and extremities. Unilateral palmar involvement with pruritus is infrequent. We report here on a case of LN confined to the right palm, and the patient presented with multiple, pruritic, erythematous to flesh-colored, tiny papules and vesicles that mimicked pompholyx. The histopathological examination of a skin biopsy specimen showed the typical findings of LN.
