Naevus spilus as a precursor of cutaneous melanoma: report of a case and literature review.

Naevus spilus is defined as a melanocytic macule in which there are dark maculopapular speckles. We describe a patient with a superficial spreading malignant melanoma arising in a congenital naevus spilus, and review the literature on this association.

Linear unilateral basaloid follicular hamartoma.

A 36-year-old woman with a linear and unilateral cutaneous hamartoma is described. The lesions consisted of hypopigmented macules that coalesced into a linear plaque that involved only the left side of her body. Within this plaque were several pearly papules and an ulcerated area that clinically resembled basal cell carcinomas. Histologic features of the hypopigmented linear plaque included multiple and multifocal basaloid proliferations in the papillary and mid dermis. The isolated pearly papules showed the typical findings of basal cell carcinoma.

[Chagas-Mazza disease. Preliminary basic social study]. / Enfermedad de Chagas-Mazza. Estudio social básico preliminar

Chagas-Mazza disease is an endemic infection of chronic evolution and is essentially American. Its transmission by vinchuca in Argentine has created a medical, psychological and social problem of great and important significance. The basic, preliminary and social study carried out in a hospital unit, showed in the population attended, precarious socioenvironmental conditions during childhood and adolescence and the almost total lack of basic information on the disease. Interviews, inquests, questionnaires, group actions, team work, direct dialogues, counselling and guidance groups and the guiding to specialized institutions, constitute a synthesis of the task developed which, in its preliminary stage, showed sufficient reasons to continue the control of health during pregnancy, childbirth, puerperium and lactation.
