Introduction: Epidermoid cysts of the temporal bone are rare, benign and slow-growing lesions. Patient and Methods: We report the case of a 69-year-old female patient followed up for a symptomatic intradiploic epidermoid cyst of the temporal scale and left mastoid region, which had been operated on but recurred. Results: MRI demonstrated a well-limited lesion seen as a hyposignal on T1-weighted images, hypersignal on T2-weighted images, on FLAIR and on diffusion-weighted images not enhanced by gadolinium. The tumour was compressive, and bone lysis was seen on CT. Conclusion: Epidermoid cysts of the temporal bone are rare, benign lesions whose diagnosis is based on fluid signals seen on MRI but absent on FLAIR sequences.

Background: Alagille syndrome is a rare genetic syndrome, which arises due to defects in the Notch signaling pathway, resulting in liver, cardiopulmonary, renal, skeletal, and ophthalmologic problems, among others. Epidermoid cysts are rare congenital benign lesions that develop from ectopic ectodermal cell rests formed during neurulation. Case Description: A 24-year-old Alagille syndrome patient presented with hearing loss and was found to have a sizable posterior fossa mass. He underwent craniotomy for uneventful resection of the lesion, which was found to be an epidermoid cyst. Conclusion: While our case may represent a coincidental occurrence of two pathologies presenting together, given that epidermoid cysts arise from aberrant neurulation, and in light of the crucial role of the Notch signaling pathway both in normal neurogenesis and in the pathogenesis of Alagille syndrome, we hypothesize a possible association between these entities.

Osteomas are bone tumours arising from the cortical or medullary bones of craniofacial skeleton. Involvement of frontal bone and paranasal sinuses is more frequent than jaw bones. Jaw osteomas are slow growing benign lesions, which are usually asymptomatic or present as painless swelling. Those involving mandibular condyle are relatively rare and result in significant functional and aesthetic disturbances. This paper reports a case of solitary central compact osteoma of mandibular condyle in an adult Indian female patient. A comprehensive review of previously published reports is also presented.

Epidermoid cysts (congenital and acquired) are not the unusual benign lesions. But to our knowledge, this is the first report in the English literature that describes an uncommon presentation of the infected acquired epidermoid cyst (ie, punctum–associated cyst or atheroma) manifesting as unilateral facial erysipelas in a 74-year-old Caucasian female. Terminology and the “submarine sign” ultrasound appearance are also analyzed.

Epidermoid cysts are benign slow growing extra-axial tumours that insinuate between brain structures, while their occurrences in intra-axial or intradiploic locations are exceptionally rare. We present the clinical, imaging, and pathological findings in two patients with atypical epidermoid cysts. CT and MRI findings for the first case revealed an intraparenchymal epidermoid cyst that demonstrated no restricted diffusion. The second case demonstrated an aggressive epidermoid cyst that invaded into the intradiploic spaces, transverse sinus, and the calvarium. The timing of ectodermal tissue sequestration during fetal development may account for the occurrence of atypical epidermoid cysts.

Epidermoid cysts are rare benign lesions in the oral cavity that may be either congenital or acquired. The cysts are usually slow-growing and asymptomatic until becoming secondarily infected or large enough to interfere with mastication and speech. Consequently, diagnosis is often delayed. The condition is also uncommon in newborns and infants. Most of the lesions occur in the floor of the mouth and rarely in the upper lip. This report describes the case of a 29-month-old girl with a palpable mass in the inner mucosa of the upper lip. The lesion was surgically enucleated using an intraoral approach and histopathologically diagnosed as epidermoid cyst.

Abstract Epidermoid cysts (ECs) are slow-growing, benign tumors that represent <2% of all intracranial tumors. ECs can be divided into following two types: extra-axial and intra-axial. Extra-axial ECs are most often positioned in the cerebellopontine angle. Intra-axial ECs, which are also referred to as intraparenchymal ECs, are most commonly found in supratentorial structures, such as the frontal and temporal lobes, accounting for <2% of all intracranial ECs and are especially rare in children. In this report, we described a unique case of medulla oblongata EC in a child, to contribute this knowledge to the existing body of literature.

Epidermoid cysts are generally benign lesions surrounded by squamous epithelium with cystic contents. The lining of the cysts produce keratin, which resemble a cheese-like material. They typically occur in the skin and mucous membranes and are congenital in origin; iatrogenic epidermoid cysts are rare. Epidermoid cysts are usually painless and asymptomatic, and their diagnosis is based on histological examination. This paper aims to present the case report of a 23-year-old patient with an iatrogenic epidermoid cyst that occurred following tracheostomy. The importance of preoperative radiological imaging in the diagnosis of epidermoid cysts is also highlighted.

Background: Epidermoid cysts are benign slow-growing congenital lesions, constituting approximately 1% of all cranial tumors. Most of these lesions are located intradurally, while about 10–25% of them are located within the diploic spaces. Intradiploic epidermoid cysts are usually discovered incidentally and may remain asymptomatic for many years, but in rare instances, they may grow intracranially and produce brain compression. Sometimes, intradiploic epidermoid cysts may occlude the main cranial venous sinuses causing intracranial hypertension. Case Description: We present the case of a 24-year-old male harboring a paramedian right occipital intradiploic cyst with erosion of both outer and inner bony tables, which occluded the torcular herophili producing a worsening symptomatology with acute-onset diplopia from right sixth cranial nerve palsy; the patient also presented bilateral papilledema, but only reported mild headache and dizziness. Neuroradiological studies evidentiated a lesion compatible with intradiploic epidermoid cyst with intralesional hemorrhagic component, overlying and almost completely occluding the torcular herophili. Considering the fast worsening of symptomatology and the evidence of intracranial hypertension, the patient was operated on immediately after completion of clinical and radiological assessment. The lesion was radically removed with almost immediate reversal of signs and symptoms. Histopathology confirmed the diagnosis of epidermoid cyst with intralesional hemorrhagic components. Conclusion: Intradiploic epidermoid cysts may cause intracranial hypertension by occlusion of main cranial venous sinuses; intralesional hemorrhage may act as precipitating factor in occlusion of the torcular herophili, producing rapidly worsening intracranial hypertension, which requires prompt surgical treatment to reverse symptomatology. Radical surgical resection is necessary to avoid recurrence.
