Tuberculosis verrucosa cutis is a paucibacillary form of cutaneous tuberculosis that often occurs in sensitized immunocompetent individuals due to exogenous reinfection. The diagnosis is often difficult because the clinical features are often not typical and acid-fast staining test often shows negative results. Therapeutic trial with antituberculosis therapy is justified if there is strong clinical suspicion in which diagnosis can be made based on the therapeutic response. We report a 46-year-old male with erythematous verrucous plaque on the right knee and crusted erythematous plaque on the left dorsal foot that had been present for 20 years. There were neither history of previous trauma nor tuberculosis treatment. Histopathology, culture, polymerase chain reaction (PCR), Mantoux test, and chest radiograph were negative for cutaneous tuberculosis. Gamma release interferon assay showed positive result. The patient was given category 1 antituberculosis treatment and showed improvement after three weeks. Treatment was continued for 6 months and the lesion significantly regressed.

Skin whitening products market is a vast and rapidly growing industry which is estimated to worth US$ 31.2 billion by 2024. 1 The desire to obtain a fair complexion to achieve a certain standard of beauty has been in practice for ages in various countries and cultures. 2 In addition, this appearance also serves as an expression for the "good," "holy," and virtuous attributes in multiple religious worldviews. 3 As a result, it is not surprising that attempts to make the skin fairer, both through certain practices or products, continue to thrive and expand up until now.

Candidiasis is an acute or subacute fungal infection caused by fungi that belongs to candida genus, with Candida albicansbeing the most frequent causative agent. Candida kefyr is a rare cause of candidiasis which has been reported in systemic candidiasis and deep infections. However, to date, it has never been reported as a cause in dermatophytosis. We report a case of candidiasis caused by Candida kefyr in a 72-year-old woman with a chief complaint of pruritic erythematous rash on the back from one day prior to admission. Diagnosis was established based on clinical features, direct microscopic examination with 10% potassium hydroxide solution, gram staining. The fungal species was determined by carbohydrate fermentation test which showed a positive result for Candida kefyr. The patient was treated with miconazole cream and fusidic cream and showed significant clinical improvement.

Incontinentia pigmenti is a rare genodermatosis that almost exclusively affects females. The disease is caused by a mutation of the nuclear factor-κB essential modulator (NEMO) gene in the Xq-28 locus of the X chromosome. The disease can seriously affect various organs, most notably the central nervous system and eyes. Cutaneous manifestation in incontinentia pigmenti is often mild but is an important diagnostic criterion for the disease. Treatment of cutaneous symptoms of incontinentia pigmenti is often not needed because they can spontaneously resolve. However, it should be noted that early diagnosis through parameters such as cutaneous manifestations is important so that prompt diagnosis and intervention for other organs can be made to prevent further fatal complications in the future.
