A young woman presented to the office with a history of bluish discoloration involving the superior malar region bilaterally. When the bluish discoloration became darker, she would press on her cheeks resulting in excretion of "black sweat" that temporarily lightened her skin color. Examination revealed ill-defined slightly swollen soft plaques involving both superior cheeks. Upon pressure on the cheeks, a dark brown fluid was expressed. Histologic examination revealed collections of ectopic apocrine glands within mid-reticular dermis. The diagnosis of apocrine chromhidrosis was made, an uncommon cause of chromhidrosis and one in which bilateral facial presentation is rare.

In males, it causes bilateral dense pediatric cataracts, dental anomalies, and facial dysmorphisms. Females traditionally have a more subtle phenotype with discrete lens opacities as an isolated feature.

Burkitt lymphoma (BL) is an aggressive non-Hodgkin lymphoma (NHL), subdivided into endemic, sporadic, and immunodeficiency-associated forms. While jaw lesions are common in endemic BL, they are infrequent in sporadic cases, only rarely constituting the first manifestation of the disease. The aim of this study is to present a rare pediatric case of sporadic BL first manifesting as gingival swellings and tooth hypermobility and provide a review of all the published sporadic BL case reports as the first sign of disease.

Background: Neurovascular coupling (NVC), as indicated by a comprehensive analysis of the amplitude of low-frequency fluctuation (ALFF) and cerebral blood flow (CBF), provides mechanistic insights into neurological disorders. Patients undergoing peritoneal dialysis (PD) and hemodialysis (HD) often face cognitive impairment, the causes of which are not fully understood.
Methods: ALFF was derived from functional magnetic resonance imaging, and CBF was quantified using arterial spin labeling in a cohort comprising 58 patients with PD, 60 patients with HD and 62 healthy controls.
