Intestinal anisakidosis: Histopathological findings and differential diagnosis

Anisakidosis is a human zoonotic disease caused by the ingestion of raw or undercooked or not adequately salted, pickled, or smoked fish containing larval nematodes of the Anisakis species. The incidence of this infection is higher in geographical zones with traditional consumption of raw fish. However, in the last years, prevalence raised in low risk zones due to the increase popularity of Asian cuisine. According to where the larvae settle in the gastrointestinal tract, anisakidosis may have different clinical symptoms. In particular, intestinal anisakidosis may mimic several surgical conditions, including appendicitis, ileitis, diverticulitis or inflammatory bowel disease. For this reason, diagnosis is often histopathological. In the present paper, we describe the clinico-pathological findings of six novel cases of intestinal anisakidosis occurred in southern Italy, and provide clues for the differential diagnosis toward Crohns disease and eosinophilic enteritis, which have similar histopathological characteristics. Awareness of the existence of intestinal anisakidosis may facilitate its recognition and correct diagnosis, which is of fundamental importance for appropriate therapeutic approach.

Late recurrent cutaneous breast angiosarcoma in an elderly woman: A case report

Breast angiosarcomas are malignant tumours of the vascular endothelium that arise frequently following radiation therapy. Their clinical and radiological aspects are highly heterogeneous. The current study reports an unusual case, never previously reported, of a late recurrent breast angiosarcoma occurring in an 83-year old female patient 11 years after a breast-conserving surgery followed by radiation therapy for an invasive ductal carcinoma, and 5 years after her initial angiosarcoma excision. The first physician to examine the patient noted a palpable mass near the scar and, following ultrasonography, described the breast lesion as suggestive of an abscess, despite the previous history of neoplasia. Typically, recurrences of breast angiosarcoma occur within the first postsurgical year. The present patient remains alive at 25 months after her last surgical treatment, and no evidence of any local or distant disease is observable.

Rectal perforation by inadvertent ingestion of a blister pack: A case report and review of literature

The accidental ingestion of a foreign body (FB) is a relatively common condition. In the present study, we report a peculiar case of rectal perforation, the first to our knowledge, caused by the inadvertent ingestion of a blister pill pack. The aim of this report is to illustrate the difficulties of the case from a diagnostic and therapeutic viewpoint as well as its unusual presentation. A 75-year-old woman, mentally impaired, arrived at our emergency department in critical condition. The computed tomography scan revealed a substantial abdominopelvic peritoneal effusion and free perigastric air. The patient was therefore submitted to an urgent exploratory laparotomy; a 2-cm long, full-thickness lesion was identified in the anterior distal part of the intraperitoneal rectum. Hence, we performed a Hartmann’s procedure. Because of her critical condition, the patient was eventually transferred to the Intensive Care Unit, where she died after 10 d, showing no surgical complication. The ingestion of FBs is usually treated with observation or endoscopic removal. Less than 1% of FBs are likely to cause an intestinal perforation. The intestinal perforation resulting from the unintentional ingestion of an FB is often a difficult challenge when it comes to treatment, due to its late diagnosis and the patients’ deteriorated clinical condition.

Clear Cell Sarcoma Of Metatarsus.

Abstract We report a case of clear cell sarcoma in the third metatarsus of the right foot. This type of tumor is very rare and scantily reported in literature. A 42-year-old Caucasian male presented with a nodular ulcerated mass on the dorsal side of the left foot. X-rays demonstrated a nodular solid lesion which dislodged the third metatarsus. A biopsy revealed a neoplastic proliferation with a sarcoma clear cell profile; because of the aggressive nature of this type of neoplasm, we performed a trans-tibial amputation according to Bugess to achieve a better functionality for the patient. The present study underlines clinical, morphological, as well as imaging and therapeutic aspects of a rare neoplasm such as clear cell sarcoma. The location site is also quite unusual - the metatarsus of the foot. The histological and immunohistochemical data were suggestive of the diagnosis of clear cell sarcoma of metatarsus. After MRI and a bone scan, the surgical treatment suggested the extension over the forefoot and the ankle and therefore a trans-tibial amputation was made.
