Therapeutic and Diagnostic Pearls

In this session, a clinician shares key insights from diverse patient cases, highlighting diagnostic and therapeutic pearls. A notable case involves a 67-year-old man diagnosed with cutaneous sarcoidosis after presenting with skin discoloration. Treatment initially included topical tacrolimus and hydroxychloroquine, later augmented with a TNF inhibitor and narrowband UVB therapy, resulting in significant skin improvement over two years. Another case featured a 25-year-old man with acne complicated by pityrosporum folliculitis, treated with a combination of topical retinoids, benzoyl peroxide, antibiotics, and fluconazole, demonstrating the importance of targeting multiple factors in chronic skin conditions. A third case showcased a woman with hyperpigmented patches, correctly identified as lichen planus pigmentosis rather than melasma due to distinctive color variations, leading to tailored treatment approaches, including low-dose isotretinoin and laser therapies. The speaker emphasized the challenge and necessity of addressing post-inflammatory hyperpigmentation, particularly following psoriasis, illustrating successful treatments with combination therapies that led to marked improvements. The session concluded by discussing early signs of central centrifugal cicatricial alopecia (CCCA), where localized hair breakage may indicate onset. Dermatoscopic features, especially grayish-white halos, serve as vital diagnostic clues, allowing for timely intervention to preserve hair follicles. Overall, the emphasis was on the importance of accurate diagnosis, multifaceted treatment strategies, and proactive patient management.
