Persistent lip enlargement: An unusual presentation of lupus erythematosus.

Macrocheilia is a challenging problem with a variety of underlying causes that are both local and systemic, and granulomatous causes underlie the majority of cases. In this study, we report on a 31-year old man who presented with a chronic lower lip enlargement and a nodular submental erythematous lesion. He was otherwise clinically healthy. Laboratory test results were within the normal limit except for a positive anti-double stranded DNA test result. A diagnosis of cutaneous lupus erythematosus was made on the basis of histopathology and direct immunofluorescence. The lesions resolved dramatically after treatment with hydroxychloroquine. Lupus erythematosus should be considered when examining patients who present with chronic lip swelling.

Mycosis fungoides two decades after exposure to sulphur mustard: a follow-up of 1100 victims.

BACKGROUND: Sulphur mustard (SM) is an alkylating chemical warfare agent which causes acute and chronic injuries to the eyes, skin, lung and respiratory tract. OBJECTIVE: We aimed to investigate the relationship between SM poisoning and Mycosis fungoides (MF) as a late consequence. MATERIAL AND METHODS: In this retrospective study, the medical files of 1100 Iranian veterans confirmed to have exposure to SM agent during the Iraq-Iran war of the 1980s were reviewed. RESULTS: All 10 cases with MF were confirmed by clinical and histopathological examinations. The mean age of the studied subjects was 43.3 ± 9.8 (years). In comparison to MF incidence rate in Iranian general population (0.39/100 000 person-years), we found an incidence rate of 0.799/100 000 person-years for MF among those who had short-term exposure to SM. The most common sites for SM lesions were flexural and thin skin areas. The main limitation was the retrospective design. CONCLUSION: This study indicates that the risk of MF in those exposed to SM may increase over time. Therefore, their follow-up is recommended.

Isolated linear blaschkoid psoriasis.

Linear psoriasis (LPs) is considered a rare clinical presentation of psoriasis, which is characterized by linear erythematous and scaly lesions along the lines of Blaschko. We report the case of a 20-year-old man who presented with asymptomatic linear and S-shaped erythematous, scaly plaques on right side of his trunk. The plaques were arranged along the lines of Blaschko with a sharp demarcation at the midline. Histological examination of a skin biopsy confirmed the diagnosis of psoriasis. Topical calcipotriol and betamethasone dipropionate ointments were prescribed for 2 months. A good clinical improvement was achieved, with reduction in lesion thickness and scaling. In patients with linear erythematous and scaly plaques along the lines of Blaschko, the diagnosis of LPs should be kept in mind, especially in patients with asymptomatic lesions of late onset.
