Conclusion: We describe for the first time in the medical literature the expression of a new protein MYZAP in several structures in the skin, colocalizing with El Bagre-EPF autoantigens and suggesting that further studies could focus on the putative roles of this molecule in the skin.

Conclusion: This was the case of a patient with L2 ALL displaying rare clinical primary gingival mucormycosis. The patient had an unfavorable outcome because, despite treatment, the ALL activity persisted, together with severe neutropenia and thrombocytopenia. The patient died due to multiple organ failure. In hematologic patients, prognosis usually depends on the response to treatment of hematologic neoplasia.

Conclusion: In cases of recurrent lichen simplex chronicus of unknown etiology, it may be helpful to utilize direct immunofluorescence and immunohistochemistry in addition to a H&E histologic review. These combined methodologies can enhance confirmation of Gram stained bacterial infections.

Conclusion: This case of Cydnidae pigmentation is being published for its rarity. According to the authors’ knowledge, this is the fourth case reported. Such pigmentation has to be differentiated from other causes, for instance, exogenous causes of pigmentation, lentigines, acral melanoma, dermatosis neglecta, and postinflammatory hyperpigmentation. The clue to the diagnosis of this pigmentation is a detailed history of brownish, sudden-onset macules of several millimeters with streaky or tapering edges usually occurring in the monsoon season and resolving spontaneously within a week, as well as dermoscopy findings: a “stuck-on” appearance with oval to bizarre-shaped brown shiny globules and clods.
