We present a case of a papillary tumour at the cerebellopontine angle in a 41-year-old man. He
presented with left-sided facial and ear pain associated with dizziness, nystagmus and hearing
loss. CT scan of the temporal bone showed a destructive tumour at the left cerebellopontine angle.
Surgical excision was performed and the diagnosis of the endolymphatic sac tumour was made.
Endolymphatic tumour is a low grade adenocarcinoma that originates from the endolymphatic
sac. The defi nitive diagnosis requires a combination of clinical features, radiological fi nding and
pathological correlation.

Extracranial schwannomas in the head and neck region are
rare neoplasms. The tumours often present as asymptomatic,
slowly enlarging lateral neck masses and determination of
the nerve origin is not often made until the time of surgery.
Preoperative diagnosis maybe aided by imaging studies such
as magnetic resonance imaging or computed tomography,
while open biopsy is no longer recommended. The accepted
treatment for these tumors is surgical resection with
preservation of the neural pathway. We report four cases of
cervical schwannomas that we encountered at our center
during four years of period. The clinical features, diagnosis and origin, management and pathological findings of these benign tumors are discussed.

Kimura disease (KD) is a rare benign chronic inflammatory
disease that presents as a nodule mostly involving deep
subcutaneous tissue of the head and neck region with
frequent regional lymphadenopathy and peripheral blood
eosinophilia. KD shares some clinical and histopathological
similarity with angiolymphoid hyperplasia with eosinophilia
(ALHE). Consequently, KD and ALHE were once considered
variants of the same disease spectrum. We present here rare
cases of Kimura disease and ALHE involving the eyelid and
lacrimal gland and discuss their differential features.
