“…Many authors have reported incidental finding of microfilaria in breast aspirates, but breast is relative uncommon site. [ 1 9 10 ] We found three cases of microfilariae in breast aspirates. In two cases, microfilariae were found incidentally with cytology of fibroadenosis, but in one case, the cytology revealed plenty of microfilariae of W. bancrofti mixed with acute and chronic inflammatory cells, occasion granulomas in the smears [ Figure 3 ].…”

Background:Filariasis is a major health problem in India. Despite the high prevalence, microfilariae are rarely found in cytology smears. Most of the cases are incidentally found, solely or in association with other pathologies.Aims and Objectives:The study was undertaken to analyze the prevalence and cytology findings of cases of incidentally found microfilariae in cytology smears (fine-needle aspiration cytology [FNAC]/body fluids) from different body parts.Materials and Methods:This was a retrospective study over 5 years, where the cases of microfilariae in aspirates from swelling of different locations and body fluids were reviewed, and clinic-pathological data were analyzed.Results and Analysis:Out of 16,738 cases of FNAC and 882 cases of fluid cytology, 22 cases (0.124%) of incidental finding of microfilaria were documented in cytology smears. The cases were diagnosed from lymph nodes (5 cases), skin and soft tissue (4 cases), scrotal (4 cases), breast (3 cases), thyroid (2 cases), and pleural fluid (2 cases). We found eosinophilia in 15 cases (68.18%) of filarial lesions. We found two cases of incidental findings of microfilariae in association with malignant lesions.Conclusion:Filariasis should be considered as differential diagnosis of swelling of lymph nodes, skin, soft tissue, inguinoscrotal region, and other sites as well. Careful screening of cytology smears may help in detection of incidental cases in the association of other pathologies.

“…Lymphatic blockage and lymphatic obstruction resulting in lymphedema and lymphadenitis are usual mode of presentation of filariasis however extranodal filariasis is rare and has been reported in uncommon sites including skin and soft tissue swelling, breast, thyroid nodule, salivary gland, cervicovaginal smear, ovarian cyst, effusion fluids, urine, bronchial, laryngeal and pharyngeal brushings. 7,10,11 Extravasation may explain the presence of microfilariae in pericardial fluid, breast cyst fluid and bronchial aspirate. The parasites circulate in lymphatic and vascular compartments but the presence of filarial organism in tissue fluids and exfoliated surface material probably occurs owing to conditions causing lymphovascular obstruction resulting in extravasations of blood and release of microfilariae.…”

Filariasis presenting as an upper arm swelling – an unusual presentation

et al. 2018

Filariasis is a chronic disabling parasitic disease causing a major public health problem in tropical areas of Southeast Asia. It is endemic in India, China, Nepal, Indonesia, parts of Asia and Africa. In Southeast Asia it is caused mainly by W. bancrofti and Brugia species. Microfilaria is known to be present in cytology smears prepared from swelling at various sites and also in different body fluids. However, upper arm swelling as a clinical presentation of filariasis is a very rare event. If cytology smears are screened with high index of suspicion in this group of otherwise asymptomatic patients, early institution of proper treatment can both prevent the complication of the disease as well as break the chain of transmission from healthy carriers.

“…Pandit et al [ 8 ] and Azad et al [ 9 ] reported the presence of adult filarial worms in soft tissue swellings. Satpathi et al [ 10 ], Pal et al [ 11 ], Chakarbarti et al [ 3 ] and Naorem et al [ 12 ] have reported cases of adult filarial worms in the breast aspirate. Our case is an addition to this list of rare occurrence of adult gravid female worm in breast.…”

BackgroundMicrofilaria is a major public health problem in tropical and subtropical countries and is an endemic problem in India. Wuchereria bancrofti is the commonest filarial infection. In some lesions, microfilariae and adult filarial worm have been incidentally detected in fine-needle aspirates.Case presentationA 35 year old hindu female presented with lump in upper outer quadrant of left breast. Fine needle aspiration revealed two adult gravid female filarial worms.ConclusionTo our knowledge this is the first ever case report to demonstrate two live gravid female and embryoid forms in wet mount preparation.Electronic supplementary materialThe online version of this article (doi:10.1186/s13104-017-2709-3) contains supplementary material, which is available to authorized users.
