RESUMO
Porokeratosis ptychotropica is a rare variant of porokeratosis that is classically located on the gluteal and perianal regions, seldom extending to the genitalia. The authors report an atypical presentation of porokeratosis ptychotropica and discuss the use of dermoscopy in evaluating this dermatosis. Dermoscopic findings, although not specific to this variant of porokeratosis, are helpful in the differential diagnosis of other genital disorders. Histopathology, through the visualization of multiple cornoid lamellae, prevails as the gold standard for the definite diagnosis of porokeratosis ptychotropica.

The emergence of certain skin conditions belonging to the group of mucocutaneous paraneoplastic syndromes may indicate the future appearance of a previously unknown malignancy. Sweet's Syndrome and relapsing polychondritis are included in this group. Sweet's Syndrome and relapsing polychondritis are very rarely found together in the same patient. This dual occurrence is more commonly found in cancer patients with associated hematological malignancies. We report the case of a 79 year-old male with Sweet's Syndrome and relapsing polychondritis, who was subsequently diagnosed with a myelodysplastic syndrome.

Certas dermatoses, pertencentes ao grupo das síndromes paraneoplásicas mucocutâneas, podem ser o prenúncio de uma neoplasia previamente não conhecida. Tanto a síndrome de Sweet como a policondrite recidivante incluem-se neste grupo. A síndrome de Sweet e a PR são raramente encontradas em um mesmo paciente. A presença de policondrite recidivante e síndrome de Sweet em um mesmo paciente tem se revelado mais frequente em pacientes com neoplasias associadas, sobretudo hematológicas. Relata-se o caso de paciente do sexo masculino, 79 anos, com síndrome de Sweet e policondrite recidivante, em quem, subsequentemente, foi diagnosticada uma síndrome mielodisplásica.
