| Abstract|| |
Cysticercosis cellulosa cutis is caused by larval stage of Taenia solium. It most commonly affects central nervous system, muscle, and subcutaneous tissue. Here, we report a case of 70-year-old female who was misdiagnosed on ultrasound as abscess and was treated with no improvement. Later, she was diagnosed on FNAC as cutaneous cysticercosis. Hence, we report this case because of its uncommon clinical presentation and diagnostic difficulty.

| Introduction|| |
Human cysticercosis is a parasitic infection caused by the larval form of Taenia Solium, known as cysticercus cellulosae. In India, the first case of cutaneous cysticercosis was recorded by Campbell and Thomson in 1912. Here, we report a case of cysticercosis cellulosae cutis because of its atypical presentation and diagnostic difficulty.
| Case Report|| |
A 70-year-old female patient presented with multiple swellings of 4 months duration over chest, abdomen, and right hand. The lesion started as single small swelling over the right side of abdomen which gradually increased in size and number involving other areas within 4 months. On examination, multiple skin colored, firm, nontender, mobile subcutaneous nodules---10 in number varying in size from 1 to 5 cm diameter were present as shown in [Figure 1]. Eosinophil count was high. Ultrasound and CT abdomen done outside showed abscess. Repeat ultrasound showed multiple oval hyperechoic with central anechoic regions and some fluid-filled cavities suggestive of cutaneous cysticercosis as shown in [Figure 2]. FNAC was done which showed scolex, hook, cyst with surrounding fluid cavity and cyst macrophages confirming cysticercosis [Figure 3]. Retrospective history revealed eating of pork 7 years ago. Patient was started on oral albendazole 400 mg thrice daily with which there was significant resolution of lesions.

| Discussion|| |
Cysticercosis is the most common parasitic disease of the central nervous system in the world but cysticercosis cutis has been reported much less frequently. The infection is common in India, Africa, Mexico, and South America. Less than 50 disseminated cysticercosis cases have been reported worldwide.
Any age and gender may be affected but children commonly suffer because of increased chance of fomite infection. The present case was of 70-year-old female, which is of uncommon occurrence. In the majority of cases, brain, eyes, or skeletal muscle are involved. Brain is the most common location accounting for 60–90% of all cases. In the subcutaneous tissue, most commonly affected site for the lesions was upper extremity, followed by the head and neck. Our case showed involvement of subcutaneous tissue of abdomen and breast. It is also uncommon to see multiple foci present in a single individual. Our case had 10 foci of subcutaneous nodules.
The symptoms may occur 5 years after infection, but may appear even after 10--30 years. The present patient gave a history of 7 years after which she developed lesions. The clinical features depend on the location of the cyst, the cyst burden, and the host reaction. Subcutaneous cysticercosis may cause painless or painful subcutaneous nodules. Clinically, soft tissue cysticercosis can be misdiagnosed as lipoma, epidermoid cyst, abscess, pyomyositis, tuberculous lymphadenitis, neuroma, neurofibroma, sarcoma, myxoma, ganglion, or fat necrosis.
Ultrasonography (USG) is the initial and most reliable diagnostic modality for a soft tissue swelling. The most common USG appearance of soft tissue cysticercosis that was encountered by Naiket al. in their study was that of an intramuscular abscess. Hence, it is important to think of cysticercosis even when USG report shows abscess in atypical cases as in our case. 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. A study done by Pooja Kala and Prathima Khare found that it was a rare finding to see scolex on FNAC which they observed only in 1 case out of 137 cases. Our case has scolex seen on FNAC.
Treatment of soft tissue cysticercosis depends on the location of the cysts. Surgical excision is done for isolated skeletal muscle or soft tissue cysticercosis associated with abscess. Cysts that are not associated with abscess can be treated with antihelminthic medications such as albendazole or praziquantel.
| Conclusion|| |
Although cysticercosis commonly involves the central nervous system, it can affect other unusual sites like skeletal muscles, eye, heart, lungs, liver, and subcutaneous tissues. In endemic areas like ours, subcutaneous cysticercosis should be thought of as a possibility whenever a patient presents with swelling or nodule over the body. Appropriate investigations like FNAC should be performed for establishing the diagnosis. Public health education regarding personal hygiene and proper handling techniques must be encouraged.
