1/13. A case of long-term survival with stage IV small cell lung cancer and early-stage central-type squamous cell lung cancer treated by photodynamic therapy.

    The present report is on a 67-year-old man with stage IV small cell lung cancer and early-stage centrally located squamous cell cancer of the lung. He was diagnosed as small cell lung cancer with multiple metastasis to the ipsilateral lung and was found to have a central-type early-stage squamous cell cancer by bronchoscope. After obtaining a complete response to the small cell lung cancer with chemotherapy and radiotherapy, photodynamic therapy was applied to the squamous cell carcinoma, resulting in complete disappearance of the tumor. recurrence of small cell cancer occurred at the ipsilateral lung and this patient died of small cell cancer 8 years after initiation of treatment. Post mortem examination confirmed complete disappearance of squamous cell cancer treated by photodynamic therapy. This is a rare case of long-term survival with stage IV small cell lung cancer and early-stage central-type squamous cell lung cancer successfully treated by photodynamic therapy.

2/13. Follicular adenoma with squamous metaplasia and cystic change: report of a case with fine needle aspiration cytological and histological features.

    Squamous metaplasia (SM) of thyroid follicular epithelium is known to occur in a variety of non-neoplastic lesions as well in thyroid neoplasms, notably papillary carcinoma (PC). In follicular thyroid tumors, on the other hand, SM is very rare. This case describes cytological and pathological findings in a follicular adenoma (FA) that presented as a cystic lesion with extensive SM. The fine needle aspiration (FNA) cytology sample in this case yielded only necrotic material from the cystic area and squamous cells, which being mostly of immature type, were not recognised as squamous in the cytological smears. The needle missed the solid (neoplastic) component of the lesion and on the whole the cytological picture was considered to be equivocal. FA can now be added to the spectrum of thyroid lesions that can show SM. awareness of this will enable cytopathologists to consider non-papillary lesions in the differential diagnosis of thyroid nodules that yield squamous cells.

3/13. Follicular baso-squamous melanocytic tumour of the skin.

    AIMS: We describe a previously unrecognized pigmented tumour of the skin and suggest a possible relationship with the follicular bulb. methods AND RESULTS: A pigmented epithelial neoplasm clinically simulating a malignant melanoma of the skin was present in a 92-year-old woman, on her left leg. It was composed of three cell types: squamous cells with trichilemmal keratinization, basaloid cells and dendritic melanocytes. The presence of three cell types was confirmed by immunohistochemistry and electron microscopy. CONCLUSIONS: The tumour showed differentiation towards the hair follicular bulb and the descriptive term of follicular baso-squamous melanocytic tumour is suggested.

4/13. Tc-99m depreotide SPECT demonstrates photon-deficiency in the thoracic vertebrae after adjunct radiation therapy of lung cancer: correlation with MRI and bone scintigraphy.

    Fifteen months after right lobe lobectomy with adjunctive radiation therapy for squamous cell carcinoma, a patient 53-yr-old man underwent Tc-99m depreotide chest single photon emission tomography (SPECT). In addition to two focal areas of abnormally increased uptake in the right lung, the Tc-99m depreotide SPECT showed cold areas in the middle thoracic vertebrae. Photopenic areas in the 6th and 7th thoracic vertebrae were shown on a bone scintigraphy. T1 weighted magnetic resonance imaging (MRI) of the spine showed fatty replacement of the marrow and Schmorl's nodes involving the 5th to 11th thoracic vertebrae. The vertebrae are normally visualized in Tc-99m depreotide SPECT imaging study, and lung tumor is usually somatostatin receptor positive with demonstrable activity in the lung. Absent uptake in the vertebrae in the fatty replacement of the marrow and multiple and giant vertebral Schmorl's nodes in the correspondent vertebrae in MRI may reflect visualization of vertebrae due to Tc-99m depreotide localizing in the bone marrow. Of the three imaging modalities, MRI showed the widest areas of thoracic vertebral involvement. One should be aware that a cold lesion in the vertebrae on Tc-99m depreotide imaging study may result from irradiation and may indicate the presence of a benign lesion in the bone marrow.

5/13. Primary intrapulmonary spindle cell thymoma with marked granulomatous reaction: report of a case with review of literature.

    Primary intrapulmonary thymoma is a rare lesion with around 20 cases reported so far in the literature. A pure spindle cell morphology in these lesions is rarer still with only a single case recorded to date. We report herein an interesting case of a 47-year-old-man, status post surgical resection and radiotherapy for a squamous cell carcinoma of the floor of mouth, who was being followed up for a radiologic opacity in the right lower lobe of the lung. The lesion remained stable in size for almost 5 years and then an increase in size was noted. A right lower lobectomy was performed with a preoperative suspicion of metastasis. Histologic and immunohistochemical evaluation revealed a primary intrapulmonary spindle cell thymoma that displayed a prominent granulomatous reaction, a phenomenon not described so far in the literature. We discuss the possible embryologic origins and the pitfalls in diagnosis of these rare neoplasms. The remarkable granulomatous response observed in the tumor raises the possibility that similar lesions might conceivably occur in the thymus as well.

6/13. Severe colitis after administration of UFT chemotherapy for temporal bone carcinoma.

    UFT (Uftoral), a blend of uracil and tegafur, is an antitumour agent for oral administration that is presumed to maintain the concentration of 5-fluorouracil (5-FU) in tumour tissue. As a result of increased use of high-dose 5-FU-based chemotherapy for various solid tumours, complicated drug-induced colitis is more frequently observed. Dihydropyrimidine dehydrogenase (DPD) is the rate-limiting enzyme in the catabolism of 5-FU and its deficiency is responsible for the severe toxicities encountered in cancer patients receiving 5-FU. The authors present the case of a patient with locally advanced temporal bone carcinoma who developed haematochezia during a course of chemotherapy with UFT. colonoscopy of the patient showed bleeding petechia-like lesions and superficial inflammatory exudate, whilst histology revealed non-specific inflammatory changes of the colon mucosa. As the haematochezia improved with supportive treatment, neutropenia complicated the clinical picture. This patient developed life-threatening UFT toxicity without an exon-14 DPD gene mutation.

7/13. head and neck cancer with simultaneous lung cancer.

    The simultaneous occurrence of a primary malignant tumor of the lung or pulmonary metastasis in patients with head and neck cancer is uncommon. In response to the question, "Are efforts toward management of cancer in the head and neck region in a person with simultaneous malignant tumor of the lung an exercise in futility?" we present six cases evaluated at the louisiana State University health Sciences Center in Shreveport during a 19-year period. men with squamous cell cancers at both locations and locally advanced malignant tumors of the lung were predominant in this series of patients. Chemoradiation was applied because of extensive disease at one or both neoplastic sites. Long-term survival was not observed in most patients (including the aggressively treated individuals) whose malignant neoplasms were concurrently managed by non-operative means.

8/13. Synchronous anal and penile cancers.

    Malignancies of the anogenital region have similar etiology, including viral infections, sexual habits, social and educational factors. condylomata acuminata represent precancerous lesions. In the available literature, we found no cases of synchronous cancers of anus and penis reported. We report a case of synchronous cancer of the penile foreskin and cancer of the anus in a 36 year-old man. The microscopic diagnosis of the anal lesion was squamous cell cancer, basaloid type. The penile lesion was squamous cell cancer, keratinizing type. Both cancers presented with the in situ component. Immunohistochemical staining (MIB-1) and histological features (koilocytosis, acanthosis and dyskeratosis) indirectly confirmed the past viral infection. Numerous etiological similarities in anogenital cancers entail careful clinical inspection in patients with a malignant lesion in this region and suggest searching for possible other concomitant cancers or precancerous lesions.

9/13. Chronic lymphocytic leukaemia, synchronous small cell carcinoma and squamous neoplasia of the urinary bladder in a paraplegic man following long-term phenoxybenzamine therapy.

    STUDY DESIGN: A case report. OBJECTIVE: To raise awareness among spinal cord clinicians of the possible carcinogenic effect of phenoxybenzamine and of the rare occurrence of small cell carcinoma in the neuropathic bladder. SETTING: Regional spinal injuries Centre and District General Hospital, Southport, Merseyside, United Kingdom. CASE REPORT: A 28-year-old man sustained a fracture dislocation of L-1 with consequent paraplegia (ASIA impairment scale A). phenoxybenzamine treatment enabled his indwelling catheter to be discarded in favour of a penile sheath, but it caused unacceptable dizziness and was stopped after 7 years. After 20 years, he developed chronic lymphocytic leukaemia, which was treated with chlorambucil and fludarabine. After 2 years, investigation of bilateral hydronephrosis revealed a primary small cell carcinoma of the bladder with coexistent squamous dysplasia. Uraemia supervened and, declining active treatment, the patient died 3 weeks after diagnosis. CONCLUSION: phenoxybenzamine, a known carcinogen in rodents, is likely also to be carcinogenic in humans, and patients with spinal cord injury who have received the drug for any significant period of time, need close follow-up to allow early detection of cancer. phenoxybenzamine should not be prescribed on a long-term basis, and should instead be replaced with a selective alpha-blocker.

10/13. Esophageal cancer surgery in heart transplant patients.

    We herein report about 2 heart transplant patients undergoing surgical resection for esophageal cancer. Both were long-term survivors after orthotopic heart transplantation for dilated cardiomyopathy. One patient underwent a transthoracic esophagectomy and gastric pull-up for an early squamous cell carcinoma of the infracarinal esophagus. The second patient underwent a resection of the cervical esophagus and interposition of a free jejunal segment after neoadjuvant radiochemotherapy for a locally advanced squamous cell carcinoma in the cervical esophagus.
