Granulocytic sarcoma presenting as atypical mastoiditis with facial paralysis: description of a case.

We describe a case of temporal granulocytic sarcoma in a 26-year-old patient after apparent molecular remission of an acute myeloid leukaemia. He complained of otodynia with hearing loss and facial paralysis on the right side. He was treated with chemotherapy and self-transplant haematopoietic stem cells.

Latex use as an occlusive membrane for guided bone regeneration.

Latex extracted from Hevea brasiliensis was used as an occlusive membrane for guided bone regeneration. Twenty-four rabbits were divided in two groups: treated and control group. Critical size bone defects (2 cm × 1 cm) were surgically made in the rabbit calvarium.

Severe exophthalmos in trigeminal plexiform neurofibroma involving the orbit and the infratemporal fossa.

Trigeminal plexiform neurofibromas involving the orbit and the infratemporal fossa are rare tumours. An uncommon case of a plexiform neurofibroma of the trigeminal nerve occurring in a 53-year-old female patient with severe cosmetic deformity is reported. The clinical findings, neuroradiographic features, surgical management, postoperative results and follow-up of trigeminal plexiform neurofibromas are reviewed.

Inflammatory myofibroblastic tumor of the temporal bone: a histologically nonmalignant lesion with fatal outcome.

Introduction: Inflammatory myofibroblastic tumor (IMFT) of the temporal bone is an unusual but distinct clinicopathologic entity.

Case Report: We report the case of a 75-year-old patient with an IMFT located in the temporal bone. Symptoms included VI, X, XI, and XII cranial nerves palsies.

Mandibular Metastasis of a Signet Ring Cell Carcinoma of the Breast in a Patient who Underwent Bilateral Mastectomy more than 25 Years Earlier.

SUMMARY: BACKGROUND: Metastatic tumors account for less than 1% of all malignant tumors occurring in the oral cavity. CASE REPORT: The clinical case of a 94-year-old patient with a mandibular tumor is reported here. The patient had undergone bilateral mastectomy more than 25 years before.

Non-sentinel node tumor invasion in oropharyngeal and oral cancer: risk of misdiagnosis of metastasis.

Conclusion: The existence of patients with positive non-sentinel node indicates a risk of misdiagnosis of metastasis in oropharyngeal and oral cancer.

Objectives: We attempted to confirm the usefulness of sentinel lymph node biopsy (SLNB) in oropharyngeal and oral cavity cancer to detect clinically occult metastases.

Patients And Methods: Twenty-two patients with a mean age of 57 (SD=13) years were studied prospectively.

Comparative study of patients with and without sentinel lymph node biopsy (SLNB) in oral and oropharyngeal cancer: is SLNB an accurate and useful procedure?

Conclusion: Sentinel lymph node biopsy (SLNB) is a technique that facilitates the study of metastasis in oral and oropharyngeal cancer and reduces morbidity in patients affected by this pathology.

Objectives: Oral and oropharyngeal cancers are common and are frequently associated with spread to cervical lymph nodes. We attempted to confirm the usefulness of SLNB in patients suffering from squamous cell carcinoma of the oral cavity as a prognostic technique for lymph node prediction of micrometastatic invasion.

Basaloid squamous cell carcinoma of the head and neck: a clinicopathological and follow-up study of 40 cases and review of the literature.

Basaloid squamous cell carcinoma (BSCC) is a rare and aggressive variant of cancer that mainly arises in the upper aerodigestive tract. This study reviews the clinico-pathological features and follow-up of a series of cases occurring in the head and neck. During a 32-year period (1974-2005), a total of 40 BSCCs have been diagnosed in the head and neck in our Institution.

Orbital giant cell angiofibroma.

A case of giant cell angiofibroma in a 73-year-old man is reported. The tumour was located in the upper-inner quadrant of the right orbit and recurred 16 months after surgical removal. The clinicopathological features of this rare neoplasm--that is nowadays considered a variant of solitary fibrous tumour--are reviewed and briefly commented on.

Temporal bone secretory meningioma presenting as a middle ear mass.

A 44-year-old woman presented with a history of increasing left hypoacusis and sporadic vertigo. CT scan revealed a tumor occupying the mastoid, middle ear, and external auditory canal. After surgical removal, a typical secretory meningioma was diagnosed.

Primary sinonasal ameloblastoma.

A case of primary ameloblastoma of the right sinonasal tract in a 66-year-old man is reported. The tumour presented as a radiographically solid mass filling the right nasal cavity and sinuses and without continuity with maxillary alveola. After radical surgery plus postoperative radiotherapy, the patient has pursued a non-aggressive clinical course after nine months of follow-up.

Inflammatory myofibroblastic tumour of the larynx.

A case of inflammatory myofibroblastic tumour of the larynx in a 74-year old man is reported. The lesion presented as a polypoid tumour arising in the left true vocal fold. The patient died of non-tumour-related causes and the autopsy showed persistence of the laryngeal tumour.

Papillary squamous cell carcinoma of the larynx.

A case of papillary squamous cell carcinoma of the larynx in a 50-year-old man is reported. The lesion was located in the supraglottic region and grossly presented a characteristic finger-like pattern of growth. The tumour pursued an indolent clinical course, and the patient is well and free of disease after 47 months of follow-up.

[Pulmonary epidermoid carcinoma in a 22-year-old patient with multiple cutaneous metastasis].

The authors present one clinical case of lung epidermoid carcinoma with several concurrent features which are uncommon in relation to this type of neoplasia. Consequently, the age of the patient (22), the lack of known risk factors, the histologic type (little differentiated squamous) and an aggressive biologic behaviour of the tumour, preceded of multiple cutaneous metastasis, are circumstances that make this clinical case exceptional. The more significative aspects present at lung carcinoma included in this age group respect to others are analyzed.

Glandular-type inverted papilloma of the prostatic urethra.

A case of inverted papilloma of glandular type in the prostatic urethra of a 65 year-old man is reported. The case was asymptomatic and incidentally discovered on histopathologic study of transurethral resection (TUR) specimens from benign prostatic hyperplasia. The literature concerning this rare entity is reviewed and briefly commented.

Atypical carcinoid of larynx: presentation with scalp metastases.

A case of atypical carcinoid tumour of the larynx in a 72-year-old woman is presented. The neoplasm was located in the supraglottic region and was first manifest by metastases to the scalp. The presence of amyloid-like material and calcitonin-positive cells were features that resembled medullary carcinoma of the thyroid.

Meningioangiomatosis and oligodendroglioma in a 15-year-old boy.

A case of meningioangiomatosis occurring in a 15-year-old boy is reported. The patient did not show signs of neurofibromatosis on physical examination, and his medical history included only one previous episode of loss of consciousness, which was accompanied by a self-limited focal seizure. The lesion was associated with an oligodendroglioma and was incidentally discovered during the macroscopic sampling of the neurosurgical specimen.
