A case of human breast sparganosis diagnosed as Spirometra Type I by molecular analysis in Japan.

A 92-year-old Japanese woman presented with a mass in the left breast, and sparganosis was suspected by biopsy of the mass. The mass disappeared once, but it reappeared at the same site one year later. For a definitive diagnosis, the mass was surgically removed, and a sparganum-like worm was detected. The causative agent was confirmed as Spirometra Type I (most probably Spirometra mansoni) by mitochondrial DNA analysis. The serological examination also proved the case as sparganosis. Considering the presence of two Spirometra species (Type I and II) in Asia, particularly Japan, molecular analysis of the causative agents is highly recommended to understand the epidemiology, infection sources, and pathogenicity in humans in both species, if the parasite specimens are available.

Filariasis of the breast caused by Brugia pahangi: A concomitant finding with invasive ductal carcinoma.

Extralymphatic filariasis is an uncommon phenomenon that can be caused by several lymphatic filarial species, including zoonotic filaria of animal origins. In this study, we report a case of a 64-year-old Thai woman who presented with a lump in her left breast that was diagnosed with invasive ductal carcinoma. At the same time, a small nodule was found in her right breast, via imaging study, without any abnormal symptoms. A core needle biopsy of the right breast nodule revealed a filarial-like nematode compatible with the adult stage of Brugia sp. A molecular identification of the nematode partial mt 12rRNA gene and ITS1 suggested the causative species as closely related to Brugia pahangi, a zoonotic lymphatic filaria of animals such as cats and dogs. The sequence of the partial mt 12rRNA and ITS1 gene in this patient was 94% and 99% identical to the previously reported sequence of mt 12rRNA and ITS1 genes of B. pahangi. The sequence of ITS1 gene is 99% similar to B. pahangi microfilaria from infected dogs in Bangkok, which was highly suspected of having a zoonotic origin. As far as we know, this is the first case report of B. pahangi filariasis presented with a breast mass concomitantly found in a patient with invasive ductal carcinoma. This raised serious concern regarding the zoonotic transmission of filariasis from natural animal reservoirs.

Case 283: Breast Filariasis.

History A 44-year-old woman who was a resident of Bihar, which is a state in eastern India, presented to the surgical outpatient department of our hospital with a history of gradually increasing swelling of the right breast associated with redness, pain, and itching over the past month. She reported a general sense of malaise and experienced episodes of chills over the past 6 months; however, she had no documented fever. There was no history of breast trauma. No history suggestive of a possible hypercoagulable state could be elicited (she was a nonsmoker, had undergone uncomplicated normal vaginal delivery 15 years earlier, was not taking oral contraceptives, and had no history to suggest past deep venous thrombosis). General physical examination findings were unremarkable. On local examination, she was found to have diffuse enlargement of the right breast. The skin over the lateral part of the breast was erythematous and showed the presence of prominent superficial veins. On palpation, few ill-defined firm mobile masses were found in the upper outer quadrant with overlying skin induration. No skin ulceration or nipple discharge was present. Few firm and discrete lymph nodes were palpable in the right axilla. Laboratory investigations showed mild anemia (hemoglobin level, 10 g/dL; normal range, 12-15 g/dL), a total leukocyte count of 14 000 cells per microliter (14 cells × 109/L) (normal range, 4500-11 000 cells per microliter [4.5-11 cells × 109/L]), a normal differential leukocyte count (74% neutrophils [normal range, 40%-80%], 24% lymphocytes [normal range, 20%-40%], and 2% eosinophils [normal range, 1%-4%]), and an erythrocyte sedimentation rate of 31 mm per hour (normal range, 0-29 mm per hour). She underwent both mammography and US. Real-time US showed mobile structures on the series of US images obtained seconds apart. On the basis of the imaging findings, US-guided fine-needle aspiration cytology was performed to confirm the diagnosis, and appropriate treatment was instituted.

Breast Sparganosis Presenting with a Painless Breast Lump: Report of Two Cases.

Sparganosis is a parasitic infestation caused by sparganum, a plerocercoid tapeworm larva of the genus Spirometra. Since the first case of human sparganosis reported in 1908, sparganosis has been a global disease, and is common in China, Japan, and Southeast Asian countries. Consumption of raw snakes, frogs, fish, or drinking contaminated beverages are sources of human infections. Human sparganosis usually manifests in subcutaneous fat in areas such as the abdomen, genitourinary tract, and limbs. Breast sparganosis cases are rare, representing less than 2% of total cases of human infections. Complete surgical extraction of the sparganum is the treatment of choice. Because of the rarity of the disease, clinical suspicion is vital to reach the diagnosis of breast sparganosis. Here we report 2 rare cases of breast sparganosis presenting with a painless breast lump, both treated with surgical excision and sparganum extraction.

A case of mammary sparganosis due to infection with Spirometra mansoni.

The authors report the case of a 56-year-old woman with mammary sparganosis due to infection with a plerocercoid tapeworm larva of Spirometra mansoni. Magnetic resonance imaging revealed an area of heterogeneous density in outer upper quadrant of the right breast, with a high likelihood of malignancy. During surgery for the removal of a granuloma, the parasite was discovered and excised. The authors review the pathological and imaging features of mammary sparganosis.

A Rare Case; Hydatid Cyst of the Breast

Hydatid cyst is a helminthic infection caused by Echinococcus granulosus that we encounter in various organs, especially in the liver and the lungs. Hydatid cyst of the breast is seen very rarely even in regions where the disease is endemic. In this article, we aimed to present a female patient who presented with complaints of a mass in her right breast, was diagnosed as having hydatid cyst as a result of physical examination and radiological imaging methods, and was treated.

Equinococosis atípica: quiste hidatídico mamario / Atypical echinococcosis: Breast hydatid cyst

Presentamos un caso de una mujer de 33 años que consultó por una tumoración palpable y dolorosa en mama izquierda de 3 años de evolución. El diagnóstico se realizó de forma casual por el hallazgo quirúrgico macroscópicamente compatible con un quiste hidatídico de mama. La equinococosis quística aislada de mama es una entidad muy rara. Es un reto lograr un diagnóstico preoperatorio y diferenciarla de otras lesiones mamarias. Hay muy pocos casos publicados y en la mayoría, el diagnóstico de certeza se consigue tras la cirugía, dado que resulta muy complicado sospechar esta patología, únicamente, en base a la exploración clínica y la radiología

We report the case of a 33-year old patient who presented a palpable lump in her left breast for three years. The diagnosis was made by chance by the surgical finding macroscopically compatible with a breast hydatid cyst. Cystic echinococcosis of the breast is a very uncommon disease. It is a challenge to achieve a preoperative diagnosis and to differentiate it from other breast lesions. There are limited reported cases in the literature, and in majority of them the certain diagnosis is obtained postoperatively, since it is complicated to suspect this pathology based solely on clinical examination and radiological investigations

Manejo diagnóstico y terapéutico de la filariasis mamaria / Diagnostic and therapeutic management to breast filariasis

La filariasis es una enfermedad parasitaria benigna poco frecuente en los países occidentales, sobre todo la afectación mamaria es inusual. Sin embargo, aumenta la frecuencia de casos de filariasis mamaria en nuestro medio debido a las corrientes migratorias y el turismo a zonas endémicas. Nuestro objetivo es incidir en el manejo diagnóstico y terapéutico de la filariasis mamaria a propósito de un caso clínico

Filariasis is a benign parasitic disease that is unusual in western countries, especially filariasis of the breast. However, cases of breast filariasis are increasing in our environment due to greater immigration and tourism to endemic areas. We report a case of breast filariasis to describe the diagnostic and therapeutic management of this disease

Bilateral breast filariasis mimicking inflammatory breast carcinoma.

Breast is an uncommon site to be affected in filariasis. However, such cases may be encountered in endemic areas. Here, we report a case of filariasis of breast in a 55-year-old woman who was clinically mistaken for inflammatory carcinoma of the breast. Sonomammography revealed classic signs pointing towards the diagnosis of filariasis of breast, which was confirmed with microscopic examination of fine-needle aspirate. Thus, imaging played a pivotal role in correctly diagnosing and further altering the line of management.

Sparganosis of the Unilateral Breast: A Case Report.

Sparganosis is a parasitic infection caused by the sparganum, the plercercoid of the genus Spirometra. The preoperative diagnosis of breast sparganosis is difficult in most cases because it is a rare parasitic infection less than 2% of all cases. We report a 62-year-old woman case of breast sparganosis that were confirmed by surgical removal of worms from the right breast. The radiologic images of the patient also revealed characteristic features of breast sparganosis. The patient described the migrating palpable breast mass, which strongly suggested the possibility of breast sparganosis. The treatment of choice and confirmative diagnosis for sparganosis are complete surgical extraction of the sparganum irrespective of infected site. Inspection of the mass site with detailed medical history and radiological examinations are important for preoperative diagnosis of sparganosis patients.

Excision of furuncular myiasis larvae using a punch: a simple, practical and aesthetic method.

Myiasis refers to Diptera larvae infesting vertebrate animals. There are two forms of the disease: primary and secondary. In primary myiasis, fly larvae invade and develop in healthy tissue; in secondary myiasis, flies lay their eggs in skin ulcerations, and the larvae develop in tissue necrosis products. Furuncular myiasis is a type of primary myiasis. Treatment for it consists of techniques such as the production of localized hypoxia to force the emergence of the larvae, and mechanical or surgical removal of the maggots. These techniques, however, are painful and often unsuccessful. We propose a new technique for extraction of myiasis larvae, which might facilitate the surgical procedure and constitute a virtually painless and aesthetic option for the patient.

Breast filariasis or inflammatory breast carcinoma? Reaching a diagnosis.

Lymphatic filariasis is a neglected tropical disease caused by the parasite Wuchereria bancrofti. Involvement of the breast is relatively uncommon and may affect only 10% of individuals with lymphatic filariasis. We present a case of an elderly woman with breast pathology. The condition clinically appeared as a malignancy. Routine diagnostic tests including tissue histopathological studies failed to clinch a diagnosis. However, a serological test helped in identifying the pathology, which turned out to be a manifestation of breast filariasis, and aided in instituting appropriate therapy for this condition.

[Dirofilariasis of the breast: Two new cases in Tunisia]. / Dirofilariose mammaire: à propos de deux nouveaux cas en Tunisie.

Dirofilariasis is an endemic animal parasitic disease in the Mediterranean basin. Its occurrence in humans is rare; when it occurs, it is most often in cutaneous locations. We report two new cases of dirofilariasis of the breast in two Tunisian women, aged 32 and 45 years old. Both came from northern Tunisia and consulted for breast lumps. Clinical examination and imaging findings suggested benign tumors. After surgical excision, the pathology examination confirmed the diagnosis, based on the presence of Dirofilaria repens in the specimen. Dirofilariasis prevalence is probably underestimated because of its non-specific clinical presentation. Breast locations are rare and frequently consist of tumors with benign features. Surgical resection confirms the diagnosis and is the only treatment.
