Carcinoma en cuirasse is a form of cutaneous metastasis. Although this condition is rare, it is most commonly associated with breast carcinoma with local recurrence after mastectomy. Cutaneous metastasis presents most commonly a few months or years after the primary has been diagnosed. Less frequently a metastasis is diagnosed at the same time as the primary tumor or presents as the first manifestation of the disease. We report a case of carcinoma en cuirasse in a 50-year-old female who presented with elevated, finely nodular, indurated skin lesions on left anterior chest wall, axillary region and keloid - like patch on left upper arm. On further examination a breast mass was detected. Fine needle aspiration of all the lesions was performed. Cytodiagnosis was given as infiltrating duct carcinoma of breast with metastatic carcinoma involving left anterior chest wall, axilla and left upper arm. We should not disregard keloid-like or indurated patches on skin which should be investigated thoroughly.
Mucosal malignant melanoma (MMM) of the nose is extremely rare. We report a case of MMM of the nasal cavity in a 60-year-old male patient presenting with a polypoidal mass in the right nasal cavity. It was increasing gradually and obstructing breathing. A biopsy of the lesion was done with a clinical suspicion of inverted papilloma/carcinoma. Microscopy revealed features suggestive of malignant melanoma with minimal melanin pigmentation. Subsequently wide local excision was done. Diagnosis of malignant melanoma was facilitated by histochemistry and immunohistochemistry.
Inflammatory myofibroblastoma is a distinctive pseudosarcomatous lesion that occurs primarily in the viscera and soft tissue of children and young adults. It is composed of myofibroblastic spindle cells accompanied by an inflammatory infiltrate of plasma cells, lymphocytes, and eosinophils. We report a 41-year-old man who presented with progressive dyspnea and pain in the right hypochondrium for 6 months. USG abdomen revealed a well-defined hypoechoic rounded mass in the subdiaphragmatic region. CT thorax and abdomen revealed a large hypodense mass in posterosuperior aspect of the right lobe of liver, right pleural effusion and basal consolidation of the right lung. Right thoracotomy was performed. The tumor mass was arising from the right side of diaphragm. Total surgical excision was done. On histomorphology and immunohistochemical analysis, a diagnosis of inflammatory myofibroblastoma was done. Following excision the patient was completely relieved of dyspnea and pain. There was no recurrence on follow-up for 2 years.
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.
