Primary rhabdomyosarcoma of the larynx.

Sarcomas constitute fewer than 1% of the head and neck cancers. They represent less than 1% of laryngeal cancers. Primary rhabdomyosarcoma of the larynx is an extremely rare malignancy. The available literature on this medical oddity is in the form of isolated case reports only. The purpose of this article is to add another case of primary rhabdomyosarcoma of a rare site, the larynx, of which only 36 cases have so far been reported in the world literature. The present patient, an eighteen-year-old boy is only the third case being reported from India among all reported cases of rhabdomyosarcoma of the larynx in the world literature.

Extramedullary plasmacytoma of the larynx: a case report.

Of head and neck malignancies extramedullary plasmacytoma occurs in less than 1% cases. It is the rarest primary laryngeal malignancy. A 65-year-old man presented with dry cough and breathlessness for last 6 months. Direct laryngoscopic examination showed a gray-white submucosal mass in the subglottic region. Histopathological examination showed presence of pseudostratified columnar epithelium with underlying stroma having mature and immature plasma cells. The cells were mono to bi-nucleated having eccentric nuclei and condensed spoke like chromatin. Few cells had centrally placed nuclei with small but conspicuous nucleoli. Some cells resembling Reed-Sternberg cells were also seen. The patient was successfully treated with primary radical radiotherapy and showed no signs of local recurrence after a 12-month follow-up.

Scalp metastasis from squamous cell carcinoma of the cervix.

We describe a 45-year-old woman with squamous cell carcinoma of the cervix stage IIB, who was initially treated with radical radiotherapy. The patient developed multiple scalp metastases 8 months following her treatment. The scalp was involved in the disease as the sole anatomic site of distant cutaneous metastasis. The scalp lesions were treated with palliative radiotherapy. A search of the literature revealed only two cases of such distant metastatic involvement of the scalp from cervical cancer.

Nasopharyngeal presentation of renal cell carcinoma.

In this case report, we present a 50-year- old woman, who presented with severe headache as her only presenting clinical symptom due to nasopharyngeal mass. Histo-pathological evaluation of the biopsy from nasopharyngeal mass revealed clear cell carcinoma. On further evaluation, an asymptomatic mass was detected in the left kidney. The metastatic lesion was treated with palliative radiotherapy. A search of the literature revealed no reports of such unusual metastasis in the nasopharynx from a primary carcinoma of the renal origin.

Malignant schwannoma of the sinonasal tract.

Malignant Schwannoma of the sinonasal tract is an extremely rare tumour. So far, only 19 cases have been reported in the literature. We report herein a case of malignant schwannoma involving nasal cavity, maxillary antrum and ethmoid sinus in a 60-year-old male patient. The patient was treated with surgery and post-operative radiotherapy. He currently remains free of the disease 15 months after the diagnosis and twelve months after completing therapy.

Liposarcoma of the larynx treated with radiotherapy.

Liposarcoma of the larynx is an extremely rare malignancy. Only 18 cases have been reported in the literature. We herein report the first case of primary liposarcoma of supra-glottic larynx in a 53-years old male patient successfully treated with radiotherapy in August-September 1992. He currently remains free of the disease 4.5 years since the initial diagnosis.
