ABSTRACT: Canine visceral leishmaniasis is a systemic, zoonotic disease widely spread in several countries. The disease is caused by Leishmania spp., and the dog is the main reservoir of this parasite. Clinical signs in the muscle skeletal system consist of muscle atrophy, weakness, lameness, abnormal locomotion, osteitis, polyarthritis, heat and swelling of the joints, enlarged local lymph nodes and pain. In this note, a case of canine myositis of the lumbar region associated with Leishmania spp. infection is reported. Clinical signs included weakness, fever, mild dehydration, enlarged mandibular, pre-scapular and popliteal lymph nodes and a large palpable soft mass in the lumbar region, semi-adhered and not painful. Serologic diagnosis resulted reagent by indirect immunofluorescence reaction method. Findings of ultrasonography of the lower back are described, revealing the misalignment of muscle fibers, interspersed with anechoic areas compatible with edema. Local fine needle aspiration cytology was crucial for a definitive diagnosis, revealing amastigote forms. In endemic areas of leishmaniasis, clinicians should consider this disease as a differential diagnosis in the presence of musculoskeletal injuries with no apparent cause.

We aimed to evaluate appropriate strategies for interpreting fine-needle aspiration cytology (FNAC) and thyroglobulin concentrations obtained through aspiration (FNA-Tg) results based on the sonographic features of lymph nodes (LNs). Consecutive patients who underwent ultrasound-guided FNAC and FNA-Tg for metastatic LNs from differentiated thyroid carcinomas (DTCs) from January 2014 to December 2018 were reviewed retrospectively. LNs were categorized sonographically as suspicious, indeterminate, or benign. The optimal FNA-Tg cutoff for metastatic LNs was evaluated preoperatively, after lobectomy, and after total thyroidectomy. The diagnostic performances of FNA-Tg, FNAC, and their combination were analyzed based on the sonographic features of LNs. The malignancy rates of LNs were analyzed based on the sonographic features, FNAC, and FNA-Tg results. Of the 1543 LNs analyzed, 528 were benign, whereas 1015 were malignant. FNA-Tg increased the sensitivity and accuracy of FNAC for LNs. The malignancy rate of LNs found to be malignant by FNAC or elevated FNA-Tg ranged from 82% to 100%, regardless of the sonographic features. The malignancy rate of LNs with indeterminate or benign FNAC findings and low FNA-Tg were stratified according to their sonographic features. We propose a diagnostic algorithm, based on combined FNAC, FNA-Tg, and ultrasound features of LNs, for diagnosing metastatic LNs of DTCs.

Background: Lymphadenopathy refers to one or more lymph nodes that are abnormal in size, consistency or number. There are various causes for lymphadenopathy which range from benign conditions to malignant either primary or secondary from draining primary tumour. Lymphadenopathy can be localised to a single group or generalised.Methods: Prospective observational study was performed for the patients attending outpatient department of general surgery at Kamineni academy of medical sciences, LB nagar Hyderabad, Telangana with complaints of enlarged or swollen lymph nodes in the neck. This study included 46 cases. In cases where fine needle aspiration cytology was inconclusive and there was need for excision biopsy, only these cases were included in the study. After biopsy lymph node was sent for gross and microscopic examination for expert opinion from department of pathology.Results: The present study includes 46 patients in a period of two years from 01-8-2015 to 31-7-2017. Of these case tuberculosis lymphadenopathy (n=25,54.3%) was the most common aetiology followed by nonspecific chronic lymphadenopathy (n=16,34.7%) followed by some relatively rare cases and unusual presentation Schwannoma, pleomorphic adenoma, Kikuchi disease, non-Hodgkin’s lymphoma and secondaries from carcinoma tongue (n=1,2.1%).Conclusions: In the present prospective study tubercular lymphadenopathy was the most common cause for cervical lymphadenopathy followed by chronic nonspecific lymphadenopathy.

Tubercular Lymphadenitis

Background: Tuberculous lymphadenitis is the most common manifestation of extrapulmonary tuberculosis. Fine needle aspiration cytology (FNAC) is a valuable tool in diagnosis of tubercular lymphadenitis. The present study aims to determine the prevalence of different cytomorphological patterns in fine needle aspiration cytology of tubercular lymph nodes and their correlation with Acid Fast Bacilli (AFB) positivity on Ziehi-Neelsen (ZN) Staining.Methods: Fine needle aspiration cytology of 274 cases diagnosed as tubercular lymphadenitis over a period of a year were reviewed. Cytomorphological patterns were categorized into three patterns. Pattern I: Epithelioid granuloma without necrosis, Pattern II: Epithelioid granuloma with caseous necrosis and Pattern III: Caseous necrosis only. Fischer Exact test was applied to correlate cytomorphological pattern and AFB positivity.Results: Tuberculous lymphadenitis was most frequent in age group 21-30 years (24.81%). Cervical lymph nodes were the most frequent lymph nodes involved (84.67%). Pattern I was the most common cytomorphological pattern observed (49.3%). Overall AFB positivity was 28.10%. Maximum AFB positivity was seen in pattern III (73.3%).Conclusions: FNAC is the simple, cost effective and minimally invasive tool to diagnose tuberculous lymphadenitis. Study of both cytomorphological pattern and ZN staining for AFB can improve the diagnostic accuracy.
