Objective. To report a unique case of pinna squamous cell carcinoma (SCC) arising shortly after resection of atypical fibroxanthoma (AFX) at the same site. Case report. An 81-year-old gentleman presented with a nodular right pinna lesion. This was excised, and histology confirmed AFX. Ten weeks later, an ulcerative lesion appeared at the resection site. This was confirmed to be SCC. Comparative analysis revealed no morphological resemblance between the initial AFX and new SCC lesion, and there was no evidence of initial misdiagnosis. Conclusion. SCC is the most common cancer involving the pinna. Whilst prolonged sun exposure is an important risk factor for SCC, chronic inflammation and wounds are other potential sources. We postulate whether SCC could have arisen from the previous scar tissue in a manner similar to Marjolin’s ulcer. This would be a highly unusual finding in the pinna and to our knowledge unprecedented in the English literature.

Rare Malignancy

Leiomyosarcoma (LMS) of the trachea is an extremely rare malignancy with only a few reported cases in English literature. As such the diagnosis can be frequently missed or delayed. We present a case of a 69-year-old male who underwent tracheostomy for airway obstruction secondary to glottic squamous cell carcinoma and treated definitely with radiation therapy. Subsequently, the patient developed LMS of the tracheostomy site. The case further details multiple risk factors that could contribute to development of LMS including radiation exposure, prior malignancy, and chronic inflammation. These risk factors have been well established for LMS in other sites but less so in the head and neck region, which is the subject of our discussion. We also review the current guidelines for head and neck as well as limb sarcomas and discussed role of surgery or radiation and their accompanying challenges in management of this rare malignancy.

Squamous cell carcinoma of the external ear can be a potentially lethal lesion. Although it is the most common cancer involving the pinna, the variables that have the greatest impact on prognosis are still in question. We reviewed 75 cases of squamous cell carcinoma of the external ear to determine patterns of occurrence and treatment failure. Forty patients had adequate follow-up for determination of cancer control rates. Local control was successful with initial treatment in 85% of the cases. The incidence of lymph node metastases was 10%, whereas distant metastasis occurred in only one patient (2.5%). This series differs from others in that most patients were unselected and most of the lesions treated were early (less than 1 cm). The significance of positive margins after surgical excision is also analyzed.

Background: Actinic keratosis or solar keratosis is a common skin lesion caused by sun damage that progresses to squamous cell carcinoma. It has been suggested that actinic keratosis is in fact SCC in situ. Objective: This literature review was conducted to investigate the differences between actinic keratosis and squamous cell carcinoma and whether actinic keratosis should in fact be managed as squamous cell carcinoma. Methods: A literature review was conducted to assess the differences between actinic keratosis and squamous cell carcinoma. We conducted searches of Pubmed, Cochrane and Medline for articles published between January 1, 2000 and April 30, 2014, using the following search terms: actinic keratosis, solar keratosis, skin cancer, squamous cell carcinoma, dermoscopy, sun exposure, ultra violet radiation, and dysplasia. Studies published in English were selected for inclusion in this review as were additional articles identified from bibliographies. Results: It is difficult to distinguish between both actinic keratosis and squamous cell carcinoma. Perhaps a classification system for actinic keratosis including early in situ SCC type AK1, early in situ SCC type AK2 and in situ SCC type actinic keratosis is needed. Conclusion: Actinic keratosis invades the basement membrane and as such may progress into invasive SCC. Superficially actinic keratoses are not distinguishable from a superficial SCC and as such may go unrecognized or inaccurately diagnosed.

Sun Exposure

Background: The development of knowledge concerning the role of sun exposure in causing skin cancer has been a gradual one. Objective: This article reviews the article by Urbach who used manikin coated with an ultraviolet dosimeter to see exactly where on the head and neck the exposure was greatest. Conclusion: Urbach showed that the areas of greatest sun exposure on his manikins corresponded with the location of 95% of squamous cell carcinoma and 66% of basal cell carcinoma. He also clearly showed the importance of scattered sky and reflected radiation.
