RESUMEN

Incontinentia pigmenti is an uncommon X-linked dominant neurocutaneous ectodermal dysplasia. The disorder is usually lethal in males in utero, although it may occasionally occur in males with somatic mosaicsism or Klinefelter syndrome. This is a case report of a rare case of incontinentia pigmenti in a newborn male who presented with characteristic skin eruptions following Blaschko's lines. Histopathology and genetic testing confirmed the diagnosis. The management of patients with incontinentia pigmenti may require a multidisciplinary approach, and early diagnosis is of great importance.

RESUMEN

Drug eruption is defined as an adverse cutaneous eruption secondary to drug intake. The most frequent variation is a morbilliform exanthema, although the clinical presentations may vary widely. The diagnosis is clinical, why thorough medical history and assessment are essential for the risk stratification of possible adverse cutaneous reaction. In Western hospitals, the prevalence is estimated to be 2-3% of the patients. Identification of the condition is therefore important for all healthcare professionals.

RESUMEN

Eruptive melanocytic nevi (EMN) is an unusual phenomenon characterized by the abrupt development of multiple melanocytic nevi over weeks to months in association with an underlying trigger. The underlying mechanisms are not fully understood, however, they have been associated with a variety of conditions. EMN is relatively uncommon and might be underreported due to the absence of close monitoring, insufficient recognition, and the presumed benign course of the condition. We describe the first case report of acral EMN associated with a burn wound on a 2-year-old child. Familiarity is important to differentiate EMN from neoplasms.

RESUMEN

INTRODUCTION: Idiopathic scrotal calcinosis is a rare benign condition which presents with asymptomatic multiple nodules on the scrotal skin. PRESENTATION OF CASE: Our patient, a 64-year-old Indian male with Fitzpatrick skin type 4, presented with multiple nodules, which were completely surgically excised with no complications. Histological examination reveals extensive intradermal deposition of calcium surrounded by histiocytes and without cystic structure. DISCUSSION: Numerous theories about the pathogenesis have been proposed and the evidence presented suggests this is a continuum. CONCLUSION: The nature of idiopathic scrotal calcinosis is still unknown and it is up to debate whether the term "idiopathic" is appropriate for the condition.
