Histiocytic necrotizing lymphadenitis (HNL) is a rare condition presenting with lymphadenopathy and fever. We report a case of a 61-year-old male with a history of perianal abscess surgery who developed HNL postoperatively. The patient was treated with corticosteroids, leading to resolution of fever and alleviation of symptoms.

Aim: Kikuchi-Fujimoto disease (KFD) rarely affects pediatric patients and is characterized by prolonged fever and cervical lymphadenopathy. The diagnosis of KFD remains challenging and often requires an invasive biopsy. Low serum alkaline phosphatase levels have frequently been observed in patients with KFD; however, the clinical significance of low serum alkaline phosphatase levels remains unclear.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the placenta can lead to fetal distress and demise, characterized by severe trophoblast necrosis, chronic histiocytic intervillositis (CHI), and massive perivillous fibrin deposition. We aimed to uncover spatial immune-related protein changes in SARS-CoV-2 placentitis compared with CHI placentas and uncomplicated pregnancies to gain insight into the underlying pathophysiological mechanisms. Placentas were retrospectively collected from cases with SARS-CoV-2 placentitis resulting in fetal distress/demise (n = 9), CHI (n = 9), and uncomplicated term controls (n = 9).

Am J Ophthalmol Case Rep

March 2025

Department of Ophthalmology, Edward S. Harkness Eye Institute, Columbia University Irving Medical Center, New York Presbyterian Hospital, New York, NY, USA.

Purpose: We present a case of Kikuchi-Fujimoto Disease (KFD) associated with bilateral optic neuropathy progressing to vision loss.

Observations: A 17-year-old male was referred for bilateral optic nerve pallor. Eight years prior, he was diagnosed with KFD after workup for lymphadenopathy and treated with prednisolone acutely followed by long-term Plaquenil.

Background: Griscelli syndrome (GS) is a rare genetic disorder characterized by oculocutaneous albinism and variable immune dysfunction. Among three distinct types of GS, occurring due to different genetic mutations; GS type 1 presents with neurological manifestations, hemophagocytic lymphohistiocytosis (HLH) generally develops in GS type 2, and GS type 3 primarily exhibits oculocutaneous albinism. HLH, a life-threatening condition with excessive immune activation, may occur secondary to various triggers, including infections, and develop in different tissues, as well as in the testis, similar to Erdheim-Chester disease.
