BACKGROUND: Embryonal rhabdomyosarcoma (sarcoma botryoides) of the female genital tract is rare in the cervix. It tends to occur in children and young women, and appears to have a better prognosis than sarcoma botryoides of the vagina and uterus. CASE: We report a case of embryonal rhabdomyosarcoma (sarcoma botryoides) presenting ...

Rhabdomyosarcoma is one of the commonest soft tissue sarcomas of childhood, but neonatal presentation is extremely rare. This limited experience means there are no clear treatment guidelines in this age group. The authors report a boy with recurrent attacks of hematuria commencing in the neonatal period, which were shown to ...

Malignant perivascular epithelioid cell tumor (PEComa) is an extremely rare mesenchymal neoplasm mostly composed of HMB-45-positive epithelioid cells with clear-to-eosinophilic cytoplasm, a propensity for perivascular distribution and a coexpression of smooth muscle markers. The uterus seems to be one of the most prevalent sites of involvement, although only 14 cases ...

Synovial sarcoma typically develops in the deep soft tissues of the extremities in adolescents and young adults. Uncommonly, these tumors may arise (9%) in the head and neck region (9%), especially at the cervical and parapharyngeal sites. Primary synovial sarcoma of the parotid gland is a rare occurrence that may ...

The development of renal cell carcinoma in Adult Polycystic Kidney Disease (APKD) has been reported in the literature; one of the features of renal malignancy in APKD is the difficulty to make a diagnosis, and the majority of cases reported are incidental findings at surgery or autopsy. We report a ...

Melanomas of the gastrointestinal (GI) tract are very rare, and their primary or secondary nature is often difficult to establish. We report the case of a 55-year-old Caucasian female who presented with an appendiceal melanoma. To our knowledge, appendiceal localization of melanoma has never been reported. We review the literature ...

Synovial sarcoma (SS) is a malignant mesenchymal neoplasm usually involving the lower limbs of young adults. Localization in head-neck district is rare. Histologically, these are characterised by a biphasic or monophasic variant, the latter being more rare and difficult to identify. Immunohistochemistry plays a crucial role in the diagnosis. Cytogenetics ...

We present a case of acroangiodermatitis that for nearly 15 years was unrecognized and treated with skin grafting and radiotherapy. This case is also unusual in that neither venous insufficiency nor an underlying arteriovenous malformation could be demonstrated. Acroangiodermatitis is infrequently reported; a review of the literature emphasizes the similarities ...

Intrapleural administration of fibrinolytic agents has been shown to be effective and safe in the treatment of loculated parapneumonic effusions. Its use in multiloculated malignant pleural effusions has been rarely reported. We report a case of malignant multiloculated pleural effusion who failed to respond to standard chest tube drainage but ...

Osteolysis induced by particulate debris from total joint implants is typically confined to bone and benign in radiographic appearance even when extensive. However, they can extend well beyond bone in which case they can simulate malignancies owing either to mass effects and pressure on adjacent tissues or owing to the ...

Malignant melanoma metastases in the gastrointestinal tract (GIT) are found in more than 60% of autopsies on patients who have died with disseminated melanoma; however, the rate of GIT metastases detected clinically averages only 2%. This discrepancy seems to be attributed to the nonspecific symptoms and signs of GIT involvement, ...

Primary malignant melanoma of the esophagus (PMME) is an uncommon but aggressive tumor with very poor prognosis. There is no established treatment plan for the disease, which may be attributed to its rarity and aggressiveness. Surgery is the choice of treatment in early cases. Radiotherapy follows surgery, and chemotherapy has ...

Malignant fibrous histiocytoma (MFH) of bone, a relatively rare primary malignant bone tumour, is a distinct clinicopathological entity as opposed to MFH derived from soft tissue. Although the true histogenesis of this condition is still controversial, a considerable number of cases of MFH in soft tissue show positive immunohistochemical reactivity ...

Monoclonal Gammopathy (MG) in multiple myeloma (MM) is an established association but its occurrence in nonmyelomatous malignancies and other inflammatory conditions is still a subject of research. We carried out this study to detect monoclonal gammopathy in myelomatous and nonmyelomatous malignancies by adopting the triangular approach of correlating radiologic findings, ...

Malignant change in schwannoma is rare. Malignant change in a vestibular schwannoma (acoustic neuroma) is even more rare. This paper presents a case of rapidly growing vestibular schwannoma first treated by radiosurgery whose histopathology after surgical excision 42 months later showed malignant changes. Up to now, eight cases of malignancy ...

Clear cell sarcoma (CCS), also known as melanoma of soft parts, is an uncommon deep soft tissue tumor presenting typically in the lower extremities of young adults. Previous cytogenetic studies have established the specificity of the recurrent t(12;22)(q13;q12), resulting in a EWS-ATF1 fusion, for CCS. The prevalence of the EWS-ATF1 ...

Laryngeal and hypopharyngeal liposarcomas are extraordinarily infrequent tumors. To the best of our knowledge there are fewer than 40 well-documented cases reported to date. Almost all of them are well-differentiated liposarcomas, with only 2 laryngeal-hypopharyngeal dedifferentiated liposarcomas. Dedifferentiated liposarcoma is defined as a well-differentiated liposarcoma with areas of high-grade spindle ...

BACKGROUND: Sinonasal melanomas are rare neoplasms whose diagnosis may require confirmatory immunohistochemical stains. S-100 protein and HMB-45, the stains most commonly used, have varying sensitivities and specificities. Melan-A, a more recent melanoma-specific marker, may prove helpful when S-100 protein and HMB-45 stains are negative or equivocal. METHODS: Seven cases of ...
