The histologic finding of variably acid-fast coccoid forms in all the available biopsy material (skin, lymph nodes, and lung) from a case of coexisting scleroderma-like cutaneous disease (hypodermitis sclerodermiformis) and systemic sarcoidosis is reported. The morphologic size, shape, and staining characteristics of these microbes, along with the presence of the lung of 'large bodies', suggest that these microbes are cell wall deficient L forms of mycobacteria. Culture of the skin of the scleroderma-like lesion yielded Staphylococcus epidermidis, and the relationship of this isolate to the histologic findings of bacteria is discussed, as well as the possible pathogenic role played by L forms of mycobacteria in collagen disease and systemic sarcoidosis.

Sarcoidosis-Like Reaction in a Patient With Psoriatic Arthritis Treated With Adalimumab.

December 2024
Internal Medicine, Hospital Infante D. Pedro, Aveiro, PRT.
A drug-induced sarcoidosis-like reaction (DISR) is a systemic granulomatous reaction indistinguishable from sarcoidosis and is associated with the administration of a medication. It typically exhibits a temporal relationship with the initiation of the drug (an average interval of 22 months) and tends to improve upon its discontinuation. Tumor necrosis factor (TNF) antagonists, including adalimumab, have been associated with the development of DISR.

Background: Sarcoidosis is a systemic granulomatous disease of unknown cause. Natural improvement with favorable outcome is common, but a significant number of patients present with difficult to manage and progressive disease. The identification of biomarkers associated with disease activity and progression is warranted.

We describe a case of sarcoidosis in a previously healthy 39-year-old man with the development of an acute kidney injury, requiring renal replacement therapy, as the first manifestation of the disease. The course of the disease was complicated by a сatheter-associated bloodstream infection. According to the histological examination of kidney biopsy samples, granulomatous interstitial nephritis was diagnosed.

Background: Systemic inflammatory diseases (SIDs) have been reported in patients with sickle cell disease (SCD), but clinical data in children are scarce.
Objectives: To identify clinical and laboratory features at diagnosis of SID in children with SCD and to describe their evolution.
Methods: Data from children with SCD and SIDs were retrospectively collected in a French multicenter study from 1991 to 2018.
Panhypopituitarism in Neurosarcoidosis: Pituitary-Hypothalamic Involvement Successfully Managed With Rituximab.

Neurosurgery Service, Specialty Hospital of the National Medical Center Siglo XXI, Mexican Social Security Institute, Mexico City 06720, Mexico.
Neurosarcoidosis (NS) is a rare form of sarcoidosis, with isolated hypothalamic-pituitary involvement being exceptionally uncommon. We report a 20-year-old woman presenting with polyuria, galactorrhea, amenorrhea, and substantial weight loss. Hormonal evaluation revealed hypopituitarism with arginine-vasopressin deficiency and hyperprolactinemia.
