“…It is one of the most important factors associated with local recurrence. 26 As per the literature review, this is the first case of ACCs in terms of involvement of posterior cranial fossa mimicking glomus jugulare with bony erosion and breaching of posterior petrous dura. ACCs involving the 7th and 8th nerves along with lower cranial nerve involvement (9-12 th ) have not been reported till now in the literature.…”

The author describes a rare case of giant adenoid cystic carcinoma (ACC) mimicking large paraganglioma with lower cranial nerve palsy. A 60-year-old female presented with a progressive increase in postauricular swelling with unilateral hearing loss, facial deviation, difficulty in swallowing, and hoarseness of voice. MRI brain showed highly vascular infiltrating and osteolytic mass suggestive of large glomus jugulare versus sarcoma. It was completely engulfing the jugular foramen and lower cranial nerves with bony erosion of the jugular foramen and occipital condyle. The whole mastoid was filled with the tumor. On digital subtraction angiography the majority of blood supply was from the occipital branch of the external carotid artery and vertebral artery. The patient underwent percutaneous embolization followed by external carotid ligation and resection of the mass. The postoperative course was uneventful. Histopathology was suggestive of mixed ACCs. The patient received radiotherapy. After 1 year of follow up no recurrence or distant metastasis was noted.

BackgroundAdenoid cystic carcinoma (ACC), a rare tumor of epithelial cell origin, commonly arises from the major salivary glands. Uncommonly it may be found outside the salivary glands and it's especially rare in the nasal cavity.Case presentationA 71-year female had complaints of swelling at the base of nose, Fine needle aspiration (FNA) from the swelling revealed features of adenoid cystic carcinoma; cell block & IHC for CD-117 was positive.ConclusionsSino-nasal ACC (SNACC) continues to pose diagnostic and therapeutic challenges to clinicians. Due to its rarity & vague presentation, early diagnosis requires a high index of suspicion. FNA can be used as an invaluable diagnostic tool in the evaluation of these lesions. Since it’s incidence in sinonasal region is rare; our attempt to report this case will heighten the physician’s awareness of this disease, helping further treatment.

Adenoid cystic carcinomas (ADCCs) are uncommon tumors, comprising < 1% of all head-and-neck cancers and 20%–25% of all salivary cancers. The most common presenting symptom of the lesion is a slowly growing mass followed by pain due to the propensity of these tumors for perineural invasion. The tumor is most often clinically deceptive by its small size and slow growth, which actually overlies its extensive subclinical invasion and marked ability for early metastasis making the prognosis questionable, aptly referred as “wolf in sheep's clothing.” Cribriform, tubular and solid are the three recognized histopathological patterns. In ADCC, one of the important prognostic factors is the histological grade determined by the percentage of solid component in the tumor, which in the present study comprise more than 30% of the entire lesion rendering it an unfavorable prognosis.
