“…However, incidental detection of fine-needle aspiration cytology smears has been reported [8,9]. In cases of elephantiasis, occult filariasis, lymphangitis, and early stages of allergic presentations, microfilariae may not be seen on peripheral blood film examination [2,10].…”

Incidental Finding of Microfilaria in Lymph Node Cytology: A Case Report

Filariasis is a global public health problem. We routinely examine it in peripheral smears made from samples collected during the night. Though the prevalence is high, microfilariae are rarely found in cytology smears. A lymph node presenting as a filarial nodule is an unusual occurrence. Also, lymph node fine needle aspiration cytology (FNAC) with a finding of microfilariae is uncommon. We would like to report the case of incidental microfilariae finding in a patient who presented with a supraclavicular lymph node mass. The patient presented with a right supraclavicular lymph node mass of size 2 cm × 2 cm and severe fever during the night for six months. The USG-neck region revealed enlarged lymph nodes in the right supraclavicular region. She was provisionally diagnosed as a case of cervical lymph node swelling under evaluation. However, on ultrasound-guided FNAC of the lymph node, microfilariae were found incidentally. In cases where clinical presentations of filariasis are absent, FNAC may aid in the diagnosis of microfilariae in the lymph node.

“…Quite often, detection of microfilariae in superficial locations by FNAC is an incidental finding and clinically not anticipated. Microfilariae have been demonstrated in aspirates from different sites such as cervical lymph node (provisional diagnosis of tuberculosis),[ 5 ] nonhealing leg ulcer (provisional diagnosis of skin infection),[ 3 ] preauricular swelling in subcutaneous tissue (provisional diagnosis of preauricular abscess). [ 1 ] In our case, there was superficial swelling on the flexor surface of arm with a provisional diagnosis of lipoma/neurofibroma.…”

“…In the early allergic stage, microfilariae do not appear in peripheral blood and, therefore, lymph node FNAC adjacent to the area of lymphangitis and/or immunologic tests may help in early detection. [ 5 ] Monoclonal antibodies against circulating filarial antigen and molecular biology techniques such as in situ hybridization (ISH), fluorescence in situ hybridization (FISH), and polymerase chain reaction (PCR) are now available for specific diagnosis, but are available only in specialized centers.

Unusual presentation of filariasis as an abscess: A case report

Bancroftian filariasis, a tropical and subtropical disease caused by Wuchereria bancrofti, is transmitted by the culex mosquito. The disease is conventionally diagnosed by the demonstration of microfilaria in peripheral blood smear. Microfilaria and adult filarial worms have been incidentally detected in fine needle aspiration cytology (FNAC) in various locations. The disease may be missed if one is not aware of the possibility, particularly in cases where eosinophilia is absent. Therefore, clinicians and pathologists need to be more vigilant in the endemic zones for early diagnosis and the treatment of filariasis. We report here an unusual case of filariasis in a 17-year-old female with a swelling in the lower part of the left arm on the flexor surface. This highlights the chances of finding microfilaria in cytology of an unsuspected case at an unusual site. This case, in addition, stresses the fact that microfilaria may be associated with an abscess even in the absence of eosinophilia.

Filariasis continues to be a very important public health problem plaguing India. This is a tropical disease, caused primarily by Wuchereria bancrofti and few caused by Brugia malayi. Even though the prevalence of filariasis is high, it is rarely reported from the lymph nodes. We would like to report the case of a 2-year-old boy who presented with a right sided post-auricular swelling of size 2 x 2 cm since past 1 year. Routine blood investigations including peripheral smear was reported as normal. FNAC from the lymph node revealed microfilaria. This case report is to highlight the chances of finding microfilaria from an unsual site.
