Onychomycosis: A study of self-recognition by patients and quality of life.

BACKGROUND: Onychomycosis accounts for approximately half of all nail disorders and is usually asymptomatic. OBJECTIVES: To evaluate patients' recognition of fungal nail disease, concomitant fungal skin diseases, complications, and quality of life. METHODS: Patients from the fungal nail clinic were enrolled between May 2011 and April 2012. Patients' awareness of diseased nails was evaluated and the Dermatology Life Quality Index (DLQI) questionnaire was used to evaluate the impact of dermatologic disease on quality of life. RESULTS: A total of 110 patients with onychomycosis were enrolled in the study, of which 64 (58.2%) were female and the mean age was  60.8 years. The number of patients who were able to recognize the presence of onychomycosis was 71 (64.5%), while 32 (29.1%) and 7 (6.4%) were diagnosed by a dermatologist and other physicians, respectively. Multivariate analysis showed that patient recognition of the disease was significantly associated with female sex and young age. The mean DLQI score was  3.6. LIMITATION: Patient recall bias including the duration of fungal nail infection, long-term past history and previous treatment was a limitation of this study that affected DLQI scores. CONCLUSION: About half of onychomycosis patients, especially elderly males, could not recognize the disease by themselves. It is important for physicians to educate patients with risk factors for onychomycosis to recognize this condition early to prevent concomitant infection and complications, and to improve patients' well-being.

Tender cutaneous nodules of the legs: diagnosis and clinical clues to diagnosis.

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.

Granulomatous mycosis fungoides with large cell transformation misdiagnosed as leprosy.

BACKGROUND: Granulomatous mycosis fungoides is an unusual histopathological variant of cutaneous T-cell lymphoma without clinical distinction from classic mycosis fungoides. Symptoms associated with peripheral nerve involvement have rarely been reported in the literature. CASE REPORT: The authors described a case of granulomatous MF stage IIB with large cell transformation who initially presented with leprosy-like condition and chronic left peroneal neuropathy The patient received six courses ofgemcitabine with greater than 90% improvement of skin lesions. The rest of the lesions were successfully treated with local electron beam radiation. CONCLUSION: Granulomatous MF with neuropathy can be clinically misdiagnosed if there is no histopathological and immunohistochemical finding to support the diagnosis of lymphoma.
