RESUMO
RESUMEN La restricción de crecimiento fetal (RCF) es el término con el que se define a aquellos fetos que no alcanzan el potencial de crecimiento intraútero esperado debido a factores genéticos o ambientales. Dentro de las causas de RCF asociadas a la placenta encontramos mosaicismo confinado a la misma, enfermedad isquémica placentaria y anomalías estructurales a este nivel. Se presenta el caso de una paciente de 32 años con diagnóstico de RCF que asocia múltiples quistes econegativos subamnióticos en la cara fetal de la placenta. Se finaliza la gestación en semana 34 mediante cesárea electiva por ausencia de diástole en el estudio Doppler de la arteria umbilical, evidenciando cinco quistes subamnióticos de 4 a 6 cm que alteran la superficie del amnios.
ABSTRACT Fetal growth restriction (FGR) is the term used to define those fetuses that do not reach the expected intrauterine growth potential due to genetic or environmental conditions. The causes of FGR associated with the placenta are confined placental mosaicism, placental ischemic disease and placental structural abnormalities. We report a case of a 32-year-old patient with a diagnosis of FGR associated with multiple subamniotic econegative cysts overlaying the fetal plate of the placenta. The gestation is ended in week 34 by elective cesarean section due to absence of diastolic flow in the umbil-ical artery, showing five subamniotic cysts from 4 to 6 cm that disrupt the surface of the amnion.

Pseudolymphomatous folliculitis is a rare entity included among the cutaneous pseudolymphomas. A 32-year-old man, with an unremarkable medical history, presented with a two-month history of an asymptomatic solitary nodule on his left cheek. Histopathological examination demonstrated a dense nodular and diffuse dermal lymphocytic infiltrate with numerous histiocytes and dendritic cells that surrounded hypertrophic hair follicles. Pseudolymphomatous folliculitis commonly presents in the fourth decade of life, with no sex predominance, as an asymptomatic, rapidly growing and solitary red dome-shaped nodule on the face. It has a benign clinical course as the lesions usually resolve with surgical excision or regress spontaneously after incisional biopsy. Although there is no report of pseudolymphomatous folliculitis progressing into lymphoma in the literature, follow-up of these patients is recommended.
