Background: Kikuchi-Fujimoto’s disease (KFD) or histiocytic necrotizing lymphadenitis is an uncommon, benign, self-limited disease of unknown etiology, primarily affecting young women. Herein, we present the cytologic features of KFD of 2 cases that presented with different clinical pictures and discuss the cytologic differential diagnosis of this condition. Cases: Case 1 was a 17-year-old girl who presented with cervical lymphadenopathy since 6 weeks and case 2 was a 32-year-old female who had cough and axillary lymphadenopathy since 8 weeks. The fine needle aspiration (FNA) smears of both cases revealed a polymorphous lymphoid population intermingled with histiocytes, many of which showed a small size, eccentric location, crescent-shaped nuclei and abundant karyorrhectic debris in the background. A diagnosis of histiocytic necrotizing lymphadenitis was made on FNA cytology, which was confirmed by subsequent histologic examination of the lymph nodes. Conclusion: Precise diagnosis of KFD on cytologic smears is crucial as it can be mistaken for tuberculous lymphadenitis, systemic lupus erythematosus, malignant lymphoma or even metastatic carcinoma, and to avoid unnecessary investigations and potentially harmful treatment. With adequate, well-preserved samples and appropriate clinical setting, the presence of abundant karyorrhectic debris, crescentic macrophages, a polymorphous lymphoid population and absence of epithelioid cell granulomas, giant cells and neutrophils must alert the cytopathologist to arrive at a correct diagnosis.
Kaposiform hemangioendothelioma involving whole of a leg in a neonate with Kasabach-Merritt phenomenon causing limb and life-threatening situation has not been reported. One such case and its successful management is presented in this case report. Literature review is made.
Atopic dermatitis (AD) is a chronic skin disorder resulting from complex interactions between skin barrier defects and a dysregulated immune system, marked by activation of multiple T cell subsets at different stages of the disease. Until recently, the management of AD rested mainly on the judicious use of emollients, topical steroids, and topical calcineurin inhibitors in the majority of patients and systemic immunosuppressants were advocated in severely diseased. However, in the last few years, new therapeutic strategies were designed and developed to target the various steps in the chain of molecular events that lead to the AD phenotype. This review article will focus on the recent advances in the management of AD.
Tuberculosis is a multisystemic disease with varied presentations.We report a case of Tuberculous gumma masquerading as mycetoma foot in a child. A nine year old malnourished boy, who was diagnosed and treated as mycetoma foot, was reevaluated in view of persisting skin lesions. Tissue biopsy histopathology was suggestive of tuberculoid granuloma. Mycobacterium tuberculosis was isolated in tissue biopsy culture. He also had underlying dissemination with meningeal involvement. The unusual presentation and the importance of screening for underlying dissemination in children diagnosed to have eutaneous tubereulosis will be diseussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
