RESUMO
Genus Malassezia comprises of 14 species of "yeast like fungi," 13 of which are lipophilic and 1 is nonlipophilic. They are known commensals and in predisposed individuals they commonly cause a spectrum of chronic recurrent infections. They rarely also cause serious illnesses like catheter-related blood stream infections, CAPD associated peritonitis etc., Though these fungi have been known to man for over 150 years, their fastidious nature and cumbersome culture and speciation techniques have restricted research. Since the last taxonomic revision, seven new species have been added to this genus. Their ability to evade the host immune system and virulence has increased the spectrum of the diseases caused by them. These agents have been implicated as causal agents in common diseases like atopic dermatitis recently. Though culture-based research is difficult, the new molecular analysis techniques and facilities have increased research in this field such that we can devote more attention to this genus to study in detail, their characteristics and their growing implications implications in the clinical scenario.
RESUMO
Congenital generalized hypertrichosis terminalis is a rare primary hypertrichotic condition, of unknown etiology presenting in the pediatric population. Though benign in nature, there is considerable psychosocial trauma attached to this, owing to the cosmetic disfigurement it produces. The association of gingival fibromatosis and a coarse facies could further worsen the cosmesis. Thus, a multidisciplinary approach involving a psychologist, a dentist apart from the dermatologist would be mandatory. We present this rare syndrome with the purpose of getting a better insight regarding the inheritance, the clinical features and the best available treatment modalities, especially the modern and novel techniques of hair removal that could be utilized to manage such individuals.
RESUMO
Lamellar ichthyosis (LI) is an autosomal recessive disorder rarely associated with systemic organ involvement and development of carcinoma. Rickets has occasionally been described with LI owing to impaired vitamin D synthesis following altered keratinization. There has also been a high association of cutaneous cancers in patients of LI. We as Dermatologists should therefore be very meticulous while doing a full work up of these patients. We report here a case of LI associated with rickets and carcinoma of the hypopharynx.
RESUMO
We present a 55-year-old male who presented with painful non-healing ulcers on the lower lip and scrotum associated with productive cough, fever, anorexia and dysuria. Erythrocyte sedimentation rate was raised, sputum was positive for acid fast bacilli. Chest X-ray was suggestive of pulmonary tuberculosis. A prostate biopsy was also suggestive of tuberculosis. A diagnosis of disseminated tuberculosis was made and the patient showed a good response in two weeks.
