“…The most likely diagnosis was lipoma. Lipoma is the most common extratesticular lesion and MRI findings were compatible with lipoma (non-enhancing mass with identical signal intensity to fat on T1-weighted and T2-weighted images) 17. Other benign extratesticular tumours (adenomatoid tumour, fibrous pseudotumor, cellular angiofibroma, fibroma of the albuginea, leiomyoma) should be considered in the differential diagnosis.…”

“…Differential diagnosis is based on clinical criteria, biochemical results and image, being the differential histological diagnosis analysed in the discussion. Assuming that MRI has an excellent diagnostic acuity to distinguish independent paratesticular lesions,17 all data point to an extratesticular lesion, being that the main differential diagnosis is other more common paratesticular tumours.…”

This case report describes the case of a 37-year-old man that noticed an intrascrotal right mass with 1 month of evolution. During physical exam presented with a large mass at the inferior portion of the right testicle, clearly separated from the testicle, with a tender consistency and mobile. An ultrasound was performed that showed a solid and subcutaneous nodular lesion, extra testicular, heterogeneous, measuring 7.2 cm. Pelvic magnetic resonance imageMRI showed a lesion compatible with a lipoma. The patient was subjected to surgical excision of the lesion by scrotal access, having histology revealed a lipoblastoma (LB) of the scrotum. Histological diagnosis was obtained by microscopic characteristics (well-circumscribed fatty neoplasm) and immunohistochemistry (stains for CD34, S100 protein and PLAG1 were positive; stains for MDM2 and CDK4 were negative). LB is extremely rare after adolescence in any location, being this first described case of intrascrotal LB described in adulthood.

“…Men with CAF are often referred with the chief complaint of a slowly growing, painless inguinal mass. Benign tumors (including fibrous pseudotumor, adenomatoid tumor, and lipoma) and malignant tumors (including liposarcoma, rhabdomyosarcoma, leiomyosarcoma, and paratesticular metastasis) are considered as differential diagnoses in patients who have paratesticular tumors . In particular, sarcoma is the most important differential diagnosis in clinical practice because wide resection is recommended for these malignant tumors …”

“…On imaging, some findings depending on the histological appearance have been noted . On MRI, CAF demonstrates heterogeneous increased signal intensity on T2‐weighted imaging, and heterogeneous contrast‐enhanced pattern due to hypervascularity.…”

“…Benign tumors (including fibrous pseudotumor, adenomatoid tumor, and lipoma) and malignant tumors (including liposarcoma, rhabdomyosarcoma, leiomyosarcoma, and paratesticular metastasis) are considered as differential diagnoses in patients who have paratesticular tumors. 5 In particular, sarcoma is the most important differential diagnosis in clinical practice because wide resection is recommended for these malignant tumors. 6 Histologically, CAF is generally a well-marginated tumor, including short bundles of collagen, spindle-shaped cells, and many small-to middle-sized round vessels.…”

A case of inguinal cellular angiofibroma

et al. 2020

Introduction Cellular angiofibroma is a benign mesenchymal tumor that is rare and has a good prognosis. However, preoperative distinction of cellular angiofibroma from malignant tumors is difficult. Case presentation A 77‐year‐old man complained of a left inguinal mass, which was a solid, painless, mobile tumor measuring approximately 40 mm and contacted with the left spermatic cord. Based on his age, the location and imaging findings, a preoperative diagnosis of myxoid liposarcoma was made. The patient underwent left high inguinal orchiectomy with complete resection of the tumor. Histologically and immunohistochemically, the tumor had no feature of malignancy. A postoperative diagnosis of cellular angiofibroma was made. The patient remains free of disease recurrence 12 months after surgery. Conclusion Cellular angiofibroma is a benign but rare tumor, which is sometimes difficult to distinguish from malignant neoplasms. Further studies are needed to accurately preoperatively diagnose this tumor.

Proton magnetic resonance spectroscopy (MRS), considered a connection between metabolism and anatomic and functional information provided by standard MRI, gives information on various tissue metabolites and their pathologic changes. Recently, proton MRS has been added as an adjunct tool to the multiparametric protocol of scrotal MRI, providing a new insight into the extremely complex biochemical milieu of normal and abnormal testes. This article reviews proton MR spectra of normal testes, showing age and bilateralism dependence. Disturbances of various metabolic pathways in testes of infertile men resulting in alterations of metabolite peaks are discussed. Preliminary data on proton MR spectra of testicular mass lesions are presented. Level of Evidence: 5. Technical Efficacy Stage: 5.
