RESUMO
PFP with IgG-4 immunostaining is a rare paratesticular tumour. Pre-operative ultrasound scan and MRI usually confirm the benign nature of the paratesticular mass avoiding the need for radical orchiectomy. The final diagnosis is based on histology of the removed paratesticular tumour. FDG PET scan plays an important role in ruling out systematic IgG4-related disease (IgG4-RD). We describe a case of multiple paratesticular fibrous pseudotumors with IgG4 immunostaining, not associated with systemic IgG4 related disease.
RESUMO
Paratesticular liposarcomas are uncommon malignancies, often misdiagnosed preoperatively, that present as a painless scrotal mass. There is no universal consensus on their management due to scarcity of reported cases. Early detection and prompt surgical intervention provide the best disease outcome. We present the case of a 74-year-old man with a painless left testicular mass. Ultrasound and CT scan showed a paratesticular tumour. He underwent left high inguinal orchidectomy. Histopathological, immunohistochemical and cytogenetics studies confirmed the diagnosis of a Grade 2 well differentiated paratesticular liposarcoma with clear surgical margins. The case was referred to our regional sarcoma centre and currently undergoes regular follow-up.
RESUMO
Testicular sarcoidosis is a rare condition characterised by non-caseating granulomas located within the testicles. This case study reports a 44-year-old man who presented initially in 2011 with testicular pain and bilateral testicular sarcoidosis was confirmed on scrotal US. In 2019 he presented with erectile dysfunction. Scrotal ultrasound scan (US) showed bilateral testicular sarcoidosis that has not changed in size and nature when compared with US in 2011.
