Solitary Temporal Plasmocytoma: A Case Report

Abstract

Introduction: Solitary plasmacytoma is a malignant plasma cell tumor that is much rarer than multiple myeloma. The location in the vault of plasmacytoma is extremely rare. We report the case of a plasmacytoma of the cranial vault in a 53-year-old adult. Observation: A 53-year-old man consulted for tinnitus, left hypoacusis and trigeminal neuralgia of the left V2 and V3, which had been evolving for one year and was aggravated one month later by the appearance of a left temporal swelling with decreased visual acuity on the left. The MRI confirmed the existence of a lesional process of the temporal vault, in T1 iso signal, T2 hypersignal and flair, intensely and heterogeneously enhanced after injection of gadolinium. Anatomopathological study revealed a solitary temporal plasmacytoma, which was referred to oncology for further management. Discussion: Plasmacytoma is defined as an isolated malignant plasma cell tumor without clinical, biological, or radiological signs of Myeloma. Craniocerebral localization is rare and constitutes only 0.7% of all solitary plasmacytomas. Conclusion: Cranial plasmacytoma is a rare tumor that should be investigated for associated myeloma. Although the imaging appearance is not very specific, plasmacytoma should be considered in the differential diagnosis of any invasive lytic lesion of the cranial vault.

Multiple Myeloma Revealed by a Plasmacytoma of the Sphenoid Sinus in a Young Subject: Case Report

“…In all cases, biological and radiological follow-up is necessary since more than 85% of cases of plasmacytoma develop true multiple myeloma [6]. The main tests that need to be done are the blood count, the erythrocyte sedimentation rate, the electrophoresis of serum and urinary proteins, and the myelogram, which confirms the diagnosis by showing the presence of more than 10% of dystrophic plasma cells [7].…”

Рядък Случай На Солитарен Плазмоцитом На Черепа

“…Много е полезно да се знае кои пациенти с плазмоцитом на черепния покрив са изложени на риск от развитие на мултиплен миелом. Jamal et al съобщава, че връзката между плазмоцитома на калварията и развитието на мултиплен миелом е непредвидима [12]. Солитарният плазмоцитом, разположен в калварията, може да е показателен за мултиплен миелом, но може да прогресира без трансформация в мултиплен миелом в продължение на няколко години.…”
