Background Limited information exists regarding survival of Asian patients with mycosis fungoides (MF) and Sézary syndrome (SS). Objective To evaluate the epidemiology, outcome and prognostic factors of these patients. Methods A retrospective review of MF/SS cases diagnosed from 2000 to 2011 at a tertiary referral dermatology centre in Singapore was performed. Results Of 246 patients, 63% were male and the median age at diagnosis was 49 years. 73.2% were Chinese, 12.6% Indian, 6.9% Malay and 7.3% Caucasian. A total of 239 patients (97.2%) had MF and seven had SS. Median follow‐up duration was 6.3 years, and median duration of symptoms at diagnosis was 13 months. For patients with MF, the majority had early disease (92.8% stage IA–IIA). 3.8% were stage IIB, 1.7% stage III and 1.7% stage IV. Complete response to treatment occurred in 78.2%, partial response in 9.6%, persistent but non‐progressive disease in 10.0% and disease progression in 4.1% of patients. Large cell transformation occurred in 4.1% of patients. Mean overall survival during this study was 12.7 years, with death occurring in 2.5% of patients (all ≥stage IIB at diagnosis). For patients with SS, 71.4% presented with stage IVA disease, 28.6% stage IVB. Complete response to treatment occurred in 14.2%, persistent but non‐progressive disease in 28.6% and disease progression in 57.2% of patients. Mean overall survival was 3.3 years within this study, with death occurring in 42.9% of SS patients. Prognostic factors associated with favourable recurrence‐free survival were male gender (P = 0.008), early disease stage (T1) at diagnosis (P < 0.001) and absence of maintenance treatment after remission (P = 0.01). Conclusion Compared to Caucasian and East Asian cohorts, MF in South‐East Asians was diagnosed at a younger age and associated with lower mortality, largely due to greater prevalence of hypopigmented MF.

Eosinophilic pustular folliculitis of Ofuji is a recalcitrant disease typified by non-infective eosinophilic spongiosis involving the infundibular region of the hair follicle. We present a case of a 49-year-old Chinese man with known palmoplantar pustulosis and acrodermatitis continua of Hallopeau which was promptly resolved with methotrexate therapy. He returned with an erythematous papulopustular eruption with coalescence to annular plaques, occurring over the face, chest and back with active palmoplantar pustulation. Histology from skin biopsy of the palmar lesion was in keeping with palmoplantar psoriasis, while biopsy of the facial and truncal lesions revealed florid perifollicular eosinophilic congregation diagnostic of eosinophilic pustular folliculitis of Ofuji. Indomethacin was initiated with partial improvement of lesions with cyclical flares. A trial of narrowband ultraviolet-B phototherapy at a frequency of thrice weekly achieved sustained clearance of both eosinophilic pustular folliculitis and palmoplantar lesions. Indomethacin was tailed down and eventually discontinued with maintenance of narrowband ultraviolet-B therapy; this achieved successful control of the disease.
