Examination of two lesions in the anterior margin of the liver suggested that the origin of the so called "solitary necrotic" nodule lies in non-malignant tissue. An origin in sclerosing haemangioma seems probable.

The radiologic findings of a single nodule from Pneumocystis jirovecii pneumonia (PJP) have been rarely reported. We described a case of granulomatous PJP manifesting as a solitary pulmonary nodule with a halo sign in a 69-year-old woman with diffuse large B cell lymphoma during chemotherapy. The radiologic appearance of the patient suggested an infectious lesion such as angioinvasive pulmonary...

Solitary extramedullary plasmacytomas are plasma cell tumors that tend to develop in mucosa-associated lymphoid tissues including the sinonasal or nasopharyngeal regions. Primary plasmacytoma of the lung is exceedingly rare and often presents as a solitary mass or nodule in mid-lung or hilar areas and diagnosed after resection. Herein, we report a case of primary pulmonary plasmacytoma that pre...

Solitary fibrous tumor (SFT) of the pleura usually presents as a peripheral mass, in contact with the surface of the pleura. However, on occasion, it can occur separately from the pleura, in the lung parenchyma. We describe the radiological and imaging features of three SFTs of the lung, diagnosed in our department, with relevant clinical data. The diagnosis of SFT of the lung, although rare, s...

Eccrine syringofibroadenoma (ESFA) is a rare tumor originated from eccrine ductal portion [1,2]. Clinically, ESFA presents a solitary papule, nodule or plaque to multiple lesions. Cases with multiple papular or macular lesions have been often associated with hereditary ectodermal dysplasia [3]. Recent findings have classified ESFA into several groups including, solitary ESFA, multiple ESFA with...

PEN also known as ‘solitary circumscribed neuroma’ is an uncommon, sporadic, cutaneous, benign, intraneural tumor, which usually presents as asymptomatic, solitary or multiple, firm, rubbery, skin-coloured or pink, papule or nodule, commonly localized on the face or close to a muco-cutaneous junction in middle aged adults with equal sex preponderance [1]. It was first described by Reed et al in...
