Lymphocytes and sinus histiocytosis in tumor and matched lymph nodes as predictors of survival in non-small-cell lung cancer

Aim: To analyze immune cell populations in non-small-cell lung cancer (NSCLC) tumors and matched tumor-bearing and non-tumor-bearing lymph nodes (ntbLNs) to predict prognosis. Patients & methods: 71 patients with long-term disease-free survival and 80 patients with relapse within 3 years were included in this study. We used Cox regression to identify factors associated with overall survival (OS) and progression-free survival (PFS). Results: Sinus histiocytosis and tumor-infiltrating lymphocyte density in the tumor were positively associated with PFS and OS. CD4 expression in N1 (hazard ratio = 0.72; p = 0.02) and N2 (hazard ratio = 0.91; p = 0.04) ntbLNs were positively correlated with OS and PFS, respectively. Discussion: Immunological markers in ntbLNs could be used to predict survival in NSCLC.

Diagnosis of Sinus Histiocytosis with Massive Lymphadenopathy (Rosai-Dorfman Disease) by Fine Needle Aspiration Cytology in a Paediatric patient

Rosai-Dorfman Disease (RDD) is also known as Sinus Histiocytosis of Massive Lymphadenopathy(SHML). Clinically Rosai-Dorfman Disease is characterized by massive, painless, bilateral cervicallymph node enlargement, often mimics lymphoma. Microscopically, it shows dilatation of lymphaticsinuses occupied by numerous lymphocytes and proliferation of histiocytes with abundant paleeosinophilic cytoplasm containing engulfed lymphocytes or plasma cells- emperipolesis.

HISTOCYTOPATHOLOGICAL DIAGNOSIS OF ROSAI-DORFMAN DISEASE: CASE REPORT AND LITERATURE REVIEW

Sinus histiocytosis with massive lymphadenopathy (Rosai–Dorfman disease) being a rare benign proliferative self-limiting disease of the cells of macrophage-histiocyte family is of unknown etiology and presents with massive lymphadenopathy. We are hereby reporting a case of RDD presenting with massive bilateral cervical and submandibular lymphadenopathy, diagnosed by histocytopathology.

Rosai Dorfman Disease

Rosai-Dorfman disease (RDD) is referred to as Sinus Histiocytosis Massive Lymphadenopathy (SHML) of unknown origin. We are reporting a rare case of Rosai Dorfman disease, a case of 6 years old male with a history of multiple painless bilateral submandibular and cervical lymphadenopathy.
