RESUMO
BACKGROUND: Anaplastic large cell lymphoma (ALCL) is one type of lymphoma, which is characterized by the proliferation of pleomorphic large atypical lymphoid cells expressing CD30 antigen. ALCL involving skin can be either primary cutaneous disease or cutaneous involvement secondary from systemic disease. Data of clinical manifestation of cutaneous ALCL in Thai patients is limited. ALCL in Thai patients may differ from other groups of patients. OBJECTIVE: To study the clinical manifestation of cutaneous ALCL in patients of Faculty of Medicine Siriraj Hospital, Thailand. MATERIAL AND METHOD: Medical records of nine patients with histopathologic diagnosis of ALCL from skin biopsy at Faculty of Medicine Siriraj Hospital were reviewed. RESULTS: Of nine patients, four patients were diagnosed as primary cutaneous ALCL, four patients as systemic ALCL with secondary skin involvement, and one patient as combined primary cutaneous ALCL and lymphomatoid papulosis. Three primary cutaneous ALCL patients had no recurrence of disease during 6-year follow-up. However all systemic ALCL patients died at one day to 1.5 years after diagnosis. CONCLUSION: Clinical manifestation and clinical course of Thai patients with anaplastic large cell lymphoma corresponded with the data from other patient population.

BACKGROUND: "Tender cutaneous nodules of the legs" is a common manifestation in dermatology. Histopathological investigation is usually required for this condition, because clinical data are frequently insufficient to make a definite diagnosis. OBJECTIVE: To identify and analyze the causes of patients presenting with tender leg nodules and to reveal clinical clues that could help to differentiate causes. MATERIALS AND METHODS: The medical records and histopathological slides of patients presenting with tender cutaneous nodules of the legs between January 2005 and December 2007 were retrospectively reviewed. RESULTS: Of the total of 154 patients, 122 (79.2%) were female. Definite diagnoses were categorized into four groups: inflammation (84.4%); infection (5.8%); tumor (6.5%); and nonspecific (3.2%). The most common cause in the inflammation group was erythema nodosum. The infections found were Acremonium spp., Penicillium sp., Mycobacterium abscessus, Mycobacterium fortuitum and Mycobacterium leprae. The tumors included leiomyoma, leukemia cutis, and lymphomas. Clinical data that correlated with and could be used as clues for the inflammation group were female sex (P = 0.03, OR 6.43) and lower leg involvement (P = 0.03, OR 7.14). LIMITATIONS: The retrospective manner of this study is a limitation. CONCLUSION: Various inflammatory conditions, infections, and tumors can present as tender cutaneous nodules of the legs. Female sex and lower leg involvement were clinical data that could be used as clues for the diagnoses in the inflammation group. However, histopathological investigation is still crucial to determine a definite diagnosis in patients presenting with tender cutaneous nodules of the legs.

BACKGROUND: Systemic sclerosis (SSc) is a multisystem disorder that affects various organ systems. Although SSc patients have both physical and psychological illness, psychological distress is sometimes underestimated as most physicians usually pay more attention to physical problems. AIMS: To evaluate dermatology-specific health-related quality of life (QoL) in Thai patients with SSc. METHODS: SSc patients, who attended the Department of Dermatology, Siriraj Hospital, Bangkok, Thailand, between August 2009 and April 2010, were enrolled. The demographic data and skin manifestations of the patients were recorded. Skin thickness of each patient was analyzed by modified Rodnan skin score. QoL was evaluated by using the validated Thai version of dermatology life quality index (DLQI) questionnaire. RESULTS: A total of 80 patients of SSc were enrolled in this study. Twelve patients had limited SSc, while 68 patients had diffuse SSc. The mean (SD) disease duration before period of evaluation was 9 (12.8) years. The mean total of DLQI score was 6.3 (range, 0-23). Patients with low DLQI score have longer disease duration than patients with high DLQI score (P<0.05). Pain/pruritus was the most significant problem to the patients. Salt and pepper appearance was the cutaneous finding that had association with high DLQI score. CONCLUSIONS: SSc had moderate impact on patient's dermatology-specific health-related QoL. Pain, pruritus, and obvious skin findings caused a significant impairment to SSc patients. Therefore, the treatment of pain and pruritus and prominent cutaneous findings should be taken into account to improve QoL of SSc patients.
