Abstract

Squamous cell carcinoma is the most common malignant neoplasm of the upper aerodigestive tract. The disease is characterized by frequent lymphatic spread; however, blood-borne distant metastasis is rare. Isolated cutaneous metastasis is even rarer. We present two cases of oropharyngeal carcinoma that presented with cutaneous metastasis in the absence of disease recurrence. Both patients were treated with wide excision of the metastatic nodule and were disease-free at the 1.5-year follow-up. This article highlights the importance of cutaneous metastasectomy.

Abstract

Neuroendocrine carcinoma (NEC) is uncommon in the head and neck and rare in the salivary glands. In the latter location, it may manifest as pain or a palpable mass. These tumors can be quite aggressive, with a tendency toward recurrence and regional and distant metastasis. Because of the limited number of reported cases in the literature, no reliable treatment has been established. We describe the case of a 79-year-old man who presented with a persistent submandibular mass that was suspicious for a malignancy on imaging. Following surgical resection and histopathologic analysis, a diagnosis of poorly differentiated small-cell NEC was made. The patient was further treated with postoperative chemotherapy, and he exhibited no evidence of recurrence or metastasis on follow-up.

Abstract

Neuroendocrine carcinoma (NEC) can be an aggressive disease with locoregional and distant metastasis. We present this article (1) to highlight the typical presentation of NEC in head and neck primary sites such as the parotid gland, paranasal sinuses, and supraglottis and (2) to discuss the prognosis of these tumors based on their histologic subtype and stage. We base our comments on the findings of our retrospective review of the cases of 16 adults-10 men and 6 women, aged 43 to 88 years (mean: 65.8)-who had been diagnosed with pathologically confirmed NEC of the head and neck. Analysis of subtypes revealed that 11 of these patients (68.8%) had presented with poorly differentiated NEC, 4 (25.0%) with moderately differentiated NEC, and 1 (6.3%) with well-differentiated NEC. The most common primary sites were the salivary glands (n = 5; 31.3%), paranasal sinuses (n = 4, 25.0%), and larynx (n = 4). There was no statistically significant difference in survival at 24 months between the patients with moderately differentiated NEC and those with poorly differentiated NEC (37.5 vs. 35.4%; p = 0.86); at the end of the study period, the patient with well-differentiated NEC was still living, 129 months after diagnosis. Taken together, patients with stage I, II, and III disease had a combined survival of 77.8% at 12 months, which was significantly higher (p = 0.023) than the 57.1% survival at 12 months for patients with stage IV disease.

Atypical carcinoid (moderately differentiated neuroendocrine carcinoma) of the uvula

article

Abstract

Carcinoid (neuroendocrine) tumors of the head and neck rarely occur outside the larynx and, until now, none has been reported in the oral cavity. We describe what we believe is the first reported case of an atypical carcinoid tumor, or any other type of neuroendocrine carcinoma, of the uvula.

Hepatocellular carcinoma presenting as an isolated sphenoid sinus lesion: A case report

Abstract

We report a rare case of a metastatic sphenoid sinus lesion originating from an undiagnosed hepatocellular carcinoma (HCC) in a 53-year-old man who presented with gradually progressive external ophthalmoplegia. Imaging showed a right sphenoid sinus lesion infiltrating the parasellar region. Although a primary sphenoid biopsy was inconclusive, positive hepatitis B surface antigen and CT-guided fine-needle aspiration cytology suggested an HCC. A repeat endoscopic biopsy from the sphenoid with immunohistochemistry confirmed the lesion to be metastatic HCC. Metastasis to the paranasal sinuses is extremely rare, and metastasis from a liver primary even more rare. Because of clinical and radiologic similarity between the primary and metastatic lesions, metastasis to the sphenoid sinus is often undiagnosed. Patients with features suggestive of sphenoid sinus malignancy should also be evaluated for the possibility of a metastatic tumor. In this article, we emphasize the rarity of the tumor, the unusual presenting symptoms, and problems with early diagnosis.

Primary frontal sinus carcinoma with extradural anterior cranial fossa involvement

article

Abstract

Paranasal sinus carcinoma is rare, with an estimated annual incidence of less than 1 per 100,000 population. Primary frontal sinus involvement is extremely rare, accounting for only 0.3% of all paranasal sinus malignancies. A frontal sinus cancer may be mistaken for a mucocele, pyocele, or osteomyelitis. We report the case of a 48-year-old woman with a carcinoma that originated in the frontal sinus. Computed tomography and magnetic resonance imaging demonstrated bony destruction with intracranial extension but no involvement of the bulbus. The patient underwent a frontal craniotomy, tumor excision, and postoperative radiotherapy. One year later, she remained symptom-free.

Papillary thyroid carcinoma with nodular fasciitis-like stroma: A case report

Abstract

Papillary thyroid carcinoma (PTC) is the most frequently occurring malignant neoplasm of the thyroid gland and is known to have several morphologic variants. PTC with nodular fasciitis-like stroma (PTC-NFS) is one of the unusual variants of PTC, with only a few cases being reported in the literature. This neoplasm is characterized by extensive reactive stromal proliferation, which may occupy 60 to 80% of the tumor along with areas of a typical papillary carcinoma. We report a case of PTC-NFS and address the diagnostic difficulties posed by the condition's extensive reactive stromal proliferation. We also emphasize that when one encounters a fibroproliferative lesion of the thyroid, a diligent search should also be made for PTC to avoid diagnostic errors.
