“…According to Nigam & Sharma 23 the experimental granuloma found in this study is similar to the ones found in human cysticercosis by T. solium due to the description of a nodule in subcutaneous cysticercosis. The nodules are composed of an inflammatory infiltrate including neutrophils, eosinophils, lymphocytes and hystiocytes surrounded by fibrillar material.…”

SUMMARYHuman cysticercosis is one of the most severe parasitic infections affecting tissues. Experimental models are needed to understand the host-parasite dynamics involved throughout the course of the infection. The subcutaneous experimental model is the closest to what is observed in human cysticercosis that does not affect the central nervous system. The aim of this study was to evaluate macroscopically and microscopically the experimental subcutaneous cysticercosis caused by Taenia crassiceps cysticerci in BALB/c and C57BL/6 mice. Animals were inoculated in the dorsal subcutaneous region and macroscopic and microscopic aspects of the inflammatory process in the host-parasite interface were evaluated until 90 days after the inoculation (DAI). All the infected animals presented vesicles containing cysticerci in the inoculation site, which was translucent at 7 DAI and then remained opaque throughout the experimental days. The microscopic analysis showed granulation tissue in BALB/c mice since the acute phase of infection evolving to chronicity without cure, presenting 80% of larval stage cysticerci at 90 DAI. While C57BL/6 mice presented 67% of final stage cysticerci at 90 DAI, the parasites were surrounded by neutrophils evolving to the infection control. It is possible to conclude that the genetic features of susceptibility (BALB/c) or resistance (C57BL/6) were confirmed in an experimental subcutaneous model of cysticercosis.

“…The vigorous granulomatous inflammatory reaction that occurs when the larvae die is responsible for all the manifestations of clinical symptoms. 10,11 Isolated cysticercosis in the subcutaneous plane is a relatively rare form of cysticercosis but should always be kept in the differential diagnosis of subcutaneous swellings. The subcutaneous nodules are usually painless but rupture of the cyst wall causes leakage of fluid and surrounding inflammation with pain in 20% cases.…”

Pediatric population is the most susceptible age for parasitic infestation and is common in the developing nations where cleanliness and hygiene are an issue and overpopulation and overcrowding are rampantly present. The incidence of cysticercosis is high in India though the exact figures are not known. Human cysticercosis is caused by infestation with larvae of pork tapeworm Taenia solium and is endemic in India. Ingestion of raw or under cooked meat/ pork containing the cysticercosis which spreads through feco-oral route. We present a case of a 6-year-old boy who presented with an upper abdominal wall mass without any other systemic complaints. Fine Needle Aspiration Cytology (FNAC) of the patient was performed and was reported as suspicious for parasitic infestation most likely cysticercosis and was advised excision biopsy. Surgery was performed followed by histopathological examination. A diagnosis of cysticercosis in the histopathology was given. This case highlights the presence of isolated cysticercosis occurring in the abdominal wall which is a rare presentation of the disease.

“…Cysticercosis is commonly seen in the brain and eyes, which together constitute 86% of these cases [ 12 , 16 , 17 ]. The remainder is mainly located in the muscles, heart, lungs, peritoneum and breast [ 3 , 7 , 8 , 18 , 19 ]. Subcutaneous cysticercosis is a relatively rare form of cysticercosis but should always be born in mind during the evaluation of subcutaneous swellings.…”

“…The diagnosis of cysticercosis can be confirmed by fine-needle aspiration cytology (FNAC) or biopsy, which shows the detached hooklets, scolex, and fragments of the spiral wall of cysticercosis cellulosae [ 3 , 8 , 18 , 20 , 33 , 34 ]. Sometimes, the larval parts may not be seen in the specimen, but an inflammatory reaction consisting of large numbers of eosinophils and histiocytes can still be seen [ 1 , 2 , 7 , 9 , 16 , 21 ].…”

SummaryBackgroundCysticercosis is a parasitic infection caused by the larval stages of the pork tapeworm, Taenia solium. The subcutaneous form of the disease is a relatively rare clinical entity. Despite its rarity, it is imperative for a radiologist to be aware of this subcutaneous form of the disease and its various radiological patterns while evaluating any subcutaneous swelling. In this paper, we aimed to describe a typical case of ‘subcutaneous cysticercosis involving the left anterior chest wall’ with high resolution ultrasound findings. We also discussed the role of other imaging modalities in a case of subcutaneous cysticercosis. To the best of our knowledge, our case is only the second documented case report of sonological evaluation of subcutaneous cysticercosis involving the left anterior chest wall and the first case with high resolution ultrasound images of the lesion.Case ReportAn 11-year-old male presented with a painless, subcutaneous swelling over the left anterior chest wall for the last 2 months. High resolution ultrasound showed a well-defined, thin-walled, cystic lesion with an eccentric, echogenic focus in the subcutaneous plane. On change of the posture of the patient, this focus showed mobility. The hypoechoic area surrounding this cyst showed significant exudative fluid collection with diffuse, floating echoes and thin, incomplete internal septations. The adjacent soft tissues were thickened and irregular, suggestive of edema. This was followed by an excision biopsy. Histopathological examination revealed cysticercus cellulose parasite with an extensive mixed inflammatory cell infiltrate in the surrounding tissue. The patient was also administered oral antihelminthic therapy. Repeat ultrasound examination at the end of this management regimen showed complete healing with no e/o any remnant or recurrent cystic lesion, abscess or edema in the subcutaneous plane.ConclusionsSubcutaneous cysticercosis is a relatively rare form of cysticercosis but should always be born in mind during the evaluation of subcutaneous swellings. High resolution ultrasound is a valuable, safe, nonionizing, cost-effective, widely-available, and easily-reproducible imaging tool for diagnosis of subcutaneous cysticercosis. There is a wide spectrum of ultrasound patterns of subcutaneous cysticercosis. In classic cases with a cyst containing a scolex within and with a surrounding abscess, high resolution ultrasound should always be the primary mode of diagnosis, thus avoiding unnecessary fine needle aspiration cytologies.
