International Academy of Pathology (IAP)

Session Chair: Douglas Gnepp, Providence, RI, USA
Convener of Head and Neck Programme:
Ilmo Leivo, Helsinki, Finland

Case 1
Case 1
Presented by: MariaPia Foschini, Bologna
A 31 years old woman presented with a small nodule of the lower lip. The nodule was surgically removed. The patient was otherwise in good health . Personal history failed to reveal any previous pathologic condition.
Case 2
Case 2
Presented by: MariaPia Foschini, Bologna
A 66 year old female presented in 2003 with a rapidly growing nodule of the right parotid gland. At echography the nodule measured 4.5 cm. in greatest axis, had well defined margins and was interpreted as Warthin’s tumour (WT). In addition the parotid contained a second nodule measuring 1.5 cm. in greatest axis. A fine needle aspiration cytology (FNAC) was performed.
Case 3
Case 3
Presented by: Manju Prasad, Boston, MA
A 65 year old woman presented with a large, firm, painful mass in the right cheek. She underwent a total parotidectomy.
Case 4
Case 4
Presented by: Manju Prasad, Boston, MA
A 32 year old woman presented with a large swelling in the left parotid area. Past history revealed that the patient had undergone enucleation of a left parotid mass at 9 years of age that showed “calcular atrophy with sialadenitis”, and superficial parotidectomy of a recurrent mass at 15 years of age that was considered “pleomorphic adenoma”. A magnetic resonance imaging showed an 11.8 x 6 cm mass in the left parotid area extending into the infratemporal fossa and the parapharyngeal space. The mass was removed by total parotidectomy.
Case 5
Case 5
Presented by: Llúcia Alós. Barcelona
A 54 year-old man complained of a painless, rapidly growing mass in the right parotid region for 2 months. The CT-scan disclosed a tumoration 2 cm. large in the parotid gland. A fine-needle aspiration (FNA) cytology of the tumor was performed before the surgical excision of the right parotid gland.
Case 6
Case 6
Presented by: Raja Seethala, Pittsburgh, PA
An 82 year old female with slowly enlarging, painless left parotid mass that was noticed three months prior to presentation. The patient had no facial nerve paralysis and no lymphadenopathy. A computerized tomographic study with contrast showed a well delineated homogeneously hyperdense left parotid neoplasm. A fine needle aspiration was read as ‘positive for neoplasm, undetermined type.’ The patient underwent a left superficial parotidectomy.
Case 7
Case 7
Presented by: Toshitaka Nagao, Tokyo
A 70-year-old man presented with a 10-year history of a left parotid mass which had recently increased in size. There was no evidence of pain or facial nerve palsy. Computed tomography and magnetic resonance imaging showed a mass in the left parotid area, measuring 2.5 cm in diameter, the imaging quality of which was compatible with pleomorphic adenoma, but malignancy could not be ruled out.
Case 8
Case 8
Presented by: Toshitaka Nagao, Tokyo
A 57-year-old woman had an 18-month history of enlarging but painless right-sided parotid swelling. On examination there was a firm mass, measuring 45 x 40 mm, without any evidence of fixation to the adjacent tissue or facial nerve palsy. Ultrasound and computerized tomographic scan showed smoothly a circumscribed round mass within the superficial portion of the right parotid gland, accompanied by multicystic low echoic areas.
Case 9
Case 9
Presented by: Jos Hille, Cape Town
A 78-year-old male from the Eastern Cape in South Africa presents with a 2.5 cm mass in the tip of the tongue and a synchronous lesion in the tracheal area. Clinically no regional lymphadenopathy was noted.
Case 10
Case 10
Presented by: Jos Hille, Cape Town
A 25-year-old male presented with a 10 x 5cm mass in the right parotid region. The tumour had been diagnosed as a muco-epidermoid carcinoma on FNA. A radical parotidectomy and radical neck dissection with a pectoralis major flap was performed. The tumour extended deeply into the parotid bed and into the neck; it was firmly attached to the pterygoid muscles, mandibular ramus/condylar area and the external ear canal.
