“…Beyond this similarity, five cases involved the middle ear, two caused facial nerve paresis, two involved cranial nerves V or VI exclusively in the absence of lower cranial nerve injury, while two affected the lower cranial nerves without involving V or VI (21). In particular, lesions can occur exclusively in the middle ear or in the mastoid (16), and in some cases, growth patterns from these locations can resemble other tumors, such as paraganglioma (13). In particular, lesions can occur exclusively in the middle ear or in the mastoid (16), and in some cases, growth patterns from these locations can resemble other tumors, such as paraganglioma (13).…”

“…Both are associated with a survival of ≥10 years,1 accounting for approximately 2–5% of all PC disorders2 3 and are characterised by a localised proliferation of neoplastic monoclonal PCs, with no radiological evidence of additional skeletal lesions, absence of signs and symptoms of multiple myeloma (hypercalcaemia, renal insufficiency, anaemia and/or bone lesions) and a normal bone marrow examination or having less than 10% clonal PC infiltration 2. More than 80% of solitary plasmacytomas show up in head and neck area 3. Meanwhile, it is rare at skull base and, particularly, in temporal bone.…”

DesCripTionA previously healthy 33-year-old pregnant woman (32 weeks of gestational age) presented to our emergency department with right peripheral facial paralysis, diplopia and ipsilateral hemifacial anaesthesia. Also, she presented a 3-month unilateral progressive hearing loss and headache episodes. On clinical examination, she presented a grade II House-Brackmann right peripheral facial paralysis and the right otoscopy (figure 1) revealed a tympanic opacity suggestive of a reddish mass in the middle ear. Tonal audiometry documented a right conductive hypoacusia with 50 dB air-bone gap with a type b tympanogram.On the same day, she underwent a temporal bone CT in a low radiation field with plumbic apron ( figure 2A,B), and an MRI without gadolinium ( figure 3A,B,C) revealed a right temporal bone infiltrative lesion extending from the petroclivus to the cerebellopontine angle and middle ear cavity. A right tympanotomy biopsy was performed and histology showed a plasmocytoma. After thoraco-abdomino-pelvic MRI staging, no other lesions were identified, and it was staged as a solitary plasmacytoma. Caesarean delivery was planned at 35 weeks by a multidisciplinary team in order to start radical stereotactic radiotherapy (46 Gy in 4,5 weeks). Afterwards, the patient reported important symptomatic improvements with substantial neoplasm regression, with lesion regression in a new MRI ( figure 4A,B,C) and without other remaining suspicious lesions in the Positron Emission Tomography (PET) scan. Presently, she and her baby are fine, and the patient is in the normal follow-up regimen.Plasma cell (PC) neoplasms represent a spectrum of diseases characterised by clonal proliferation and accumulation of immunoglobulin-producing differentiated B cells.

“…El plasmocitoma es una patología rara que pertenece al grupo de neoplasias malignas de células plasmáticas. Corresponde alrededor del 4% de todos los tumores de las células plasmáticas 1 , y se puede considerar como la lesión precursora del mieloma múltiple 2 , con una tasa de diseminación de mieloma múltiple que oscila entre el 8% y el 50%. Dependiendo del origen de las células neoplásicas, los plasmocitomas solitarios se dividen en plasmocitoma óseo solitario y plasmocitoma extramedular.…”
