Epithelioid hemangioendothelioma (EHE) is a rare tumor of vascular origin. While it can be found in any tissue, it is most often found in lung and liver and usually has an intermediate behavior. EHEs originating from pleural tissue have been less frequently described than those from other sites. Furthermore, to date, all of the cited pleural EHEs were described as highly aggressive. In the present report, we describe a rare case of pleural EHE extending to lung and bone in a 31-year-old woman. The histological diagnosis was confirmed by both conventional examination and immunohistochemistry. Her disease stabilized during the 4th course of adriamycin (45 mg/m2, day 1-3), dacarbazine (300 mg/m2, day 1-3) and ifosfamide (2,500 mg/m2, day 1-3) with mesna, and she survived for 10 months after the diagnosis.
HighlightsCoelomic metaplasia is considered to be one of the mechanisms resulting in endometriosis.Intense ceolomic metaplasia resulted in a uterine like mass (ULM) acquiring the structural integrity of a miniature uterus.ULM might be considered a rare manifestation in the spectrum of endometriosis development.
Sparganosis is an infestation caused by a tapeworm belonging to the genus Spirometra. The typical radiologic findings of sparganosis describe elongated, folded, band or tubular, hypoechoic structures with surrounding increased echogenicity in ultrasonography. These imaging features have been highly consistent with pathology results. Here, we report an interesting case of axillary sparganosis that manifested changes on ultrasound images over a period of 6 months.
Meningioma originates from arachnoid cap cells and is the second most common intracranial tumor; however, it can also be found in an extracranial location. A very rare primary extracranial meningioma without the presence of an intracranial component has also been reported. Primary extracranial meningiomas have been found in the skin, scalp, middle ear, and nasal cavity. A computerized tomography or magnetic resonance imaging scan is necessary to determine the presence or absence of an intracranial meningioma, and a biopsy is essential for diagnosis. We report a case of primary extracranial meningioma located in the forehead skin of a 51-year-old male.
Localized primary breast amyloidosis is a very rare benign disease characterized by abnormal protein deposition in the mammary glands. Amyloidosis may mimic the appearance of a number of pathologies, both benign and malignant. Clinically, the patient may present with a breast mass or simply with increased breast density and skin thickening. Herein, we report the case of a 45-year-old woman who presented with a breast mass and was ultimately diagnosed with primary breast amyloidosis, and the mass diagnosed with amyloidosis increased in size and there were a greater number of amorphous and irregular microcalcifications on mammography and ultrasound at the 1-year follow-up. To conclude, we presented changes in a case of localized primary breast amyloidosis on mammography and ultrasound images over a period of 1 year. The current standard of care of primary breast amyloidosis is surgical resection; however, the patient should be followed after surgery to monitor the possibility of recurrence of malignancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
