Periorbital squamous cell carcinoma with orbital invasion

Predictors of Thyroid Gland Invasion in Laryngeal Squamous Cell Carcinoma

Introduction: Laryngeal squamous cell carcinoma (SCC) can invade the thyroid gland leading to unnecessary thyroidectomies with subsequent hypothyroidism and hyperparathyroidism. Thus, clinicopathological variables should be defined in order to predict thyroid gland invasion preoperatively.   Materials and Methods: We performed a retrospective analysis of 1,465 patients with laryngeal SCC referr...

Squamous cell carcinoma presenting as an orbital cyst with radiologic evidence of perineural invasion.

PURPOSE To report clinical and radiologic findings of cystic squamous cell carcinoma (SCC) of the orbit with evidence of perineural involvement. METHODS Analysis of clinical findings and radiology with a literature review. RESULTS A 66-year-old man with SCC of the forehead 8 years prior presented with paraesthesias, diplopia, and proptosis. Magnetic resonance imaging showed a well-defined, ...

Squamous cell carcinoma of lung with unusual site of metastasis

Background: Lung cancer ranks among the most common and most lethal malignancies worldwide. Once vascular or lymphatic invasions occur, metastatic dissemination to distant sites is common. Bone, liver, adrenals, and brain are the most frequent sites of the distant disease. In this study we present a case of squamous cell carcinoma of lung with metastasis of the left knee bursa.Case presentation...

Cutaneous Squamous Cell Carcinoma with Invasion through Ear Cartilage

Cutaneous squamous cell carcinoma of the ear represents a high-risk tumor location with an increased risk of metastasis and local tissue invasion. However, it is uncommon for these cancers to invade through nearby cartilage. Cartilage invasion is facilitated by matrix metalloproteases, specifically collagenase 3. We present the unusual case of a 76-year-old man with an auricular squamous cell c...
