Chromoblastomycosis: A Rare Presentation With Polymorphic Cutaneous Lesions And Bone Involvement, Caused By Exophiala Janselmei.

Chromoblastomycosis, a chronic fungal infection of skin and subcutaneous tissue arises as a result of traumatic inoculation of exposed areas of the body. We present a unique case of chromoblastomycosis caused by Exophiala janselmei in a female farmer who presented with multiple smooth non-tender nodules on trunk and limbs for 5 years and pigmented indurated plaques on her face for 2 years along with deformities of her hands. Imaging investigations revealed multiple lytic lesions in the bones of the upper and lower limbs. Histopathological findings showed characteristic sclerotic bodies, consistent with the diagnosis of chromoblastomycosis. She was started on a combination of oral antifungals with a good response. This case highlights the importance of high suspicion and early diagnosis of deep fungal infections in order to avoid disfigurement and comorbidities.

Association of Vitamin D with Moderate to Severe Acne Vulgaris.

OBJECTIVE: To determine the association of vitamin D deficiency in moderate to severe acne. STUDY DESIGN: A comparative study. Place and Duration of the Study: Dermatology OPD at Dow University of Health Sciences, Karachi, Pakistan, from December 2021 to May 2022. METHODOLOGY: Fifty patients with moderate acne, 50 patients with severe acne, and 50 healthy controls were inducted. Information regarding age, gender, and medical and medication history were taken. The severity of acne was rated according to the GAGS (global acne grading system) score. Levels of 25(OH) D were classified as sufficient (>20 ng/mL), insufficient (12-20 ng/mL), or deficient (<12 ng/mL). Significance was taken at p-value <0.05. RESULTS: The median concentration of vitamin D levels was 7.09 ng/ml in severe acne vulgaris, 13.7 ng/ml in moderate acne vulgaris and 21.6ng/ml in the control group. Serum vitamin D levels were significantly lower (p<0.001) in individuals with acne vulgaris as compared to the healthy controls. However, the decrease in level of vitamin D did not correspond with the severity of acne vulgaris. CONCLUSION: Vitamin D deficiency is additionally pronounced in acne vulgaris individuals, but vitamin D levels are not proportional to the severity of acne vulgaris. KEY WORDS: Acne vulgaris, Vitamin D deficiency, Pilosebaceous unit, GAGS score.
