Lupus mastitis is an uncommon presentation of lupus erythematosus profundus (LE profundus), characterized by inflammation of the subcutaneous fat. LE profundus occurring as initial manifestation of LE is rare. We report a case where the patient presented with lupus mastitis and years later, she developed disseminated discoid LE (DLE) and polyarteritis nodosa (PAN). PAN and DLE are connective tissue diseases with different etiologies, clinical, immunological, and histopathological features. One connective tissue disease evolving into another is rare, and the reasons remain unexplained. This woman had histopathologically proven DLE and lupus mastitis with a negative antinuclear antibody profile. She satisfied the American College of Rheumatology criteria for PAN.
Background: Pityriasis versicolor (PV) is a mild chronic infection of the skin caused by Malassezia yeasts, and characterized by discrete or confluent scaly, discolored or dyspigmented areas, mainly on the upper trunk. Wood’s lamp examination and potassium hydroxide (KOH) smear are essential tools to diagnose certain cases of PV. KOH smear examination is simple but may be difficult to interpret sometimes. Lactophenol cotton blue (LPCB) mount helps to visualize the hyphae and spores more clearly4. Hence, this study was conducted to assess the clinical features, epidemiological factors as well as KOH smear and LPCB findings in cases of PV. Aims and Objectives: To study the clinicomycological and epidemiological profile of PV in patients attending the department of Dermatology and Venereology, Government medical college, Kottayam. Materials and Methods: A descriptive cross-sectional study was done for a period of 18 months. All clinically diagnosed cases of PV were included in the study. A detailed history taking and clinical examination to asses the epidemiological parameters and to find any predisposing factors was done. Scrapings were taken for KOH smear demonstration and LPCB mount. The characteristics of hyphae were studied. Results: Peak incidence of disease was seen in 2nd and 3rd decade with a male preponderance. Most of the patients were asymptomatic with hypopigmented type on the trunk with positive stretch sign. Seborrheic dermatitis was the most common association. KOH mount and LPCB stain demonstrated hyphae in more than 90%. Conclusion: PV is a disease of younger age with hypopigmented macule on trunk being the commonest presentation. KOH mount and LPCB stain are useful tool in diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
