Introduction Inverted papillomas (IP) are benign sinonasal neoplasms, which account for 0.5–4% of all nasal tumors. IPs have been known to transform into squamous cell carcinoma in 5–15% of cases. Rarely, transformations to other malignancies have been reported. Here we report a unique case of malignant transformation of an IP into sinonasal undifferentiated carcinoma (SNUC). Methods A case report with a literature review; institutional review board exempted. The clinical presentation, radiographic features, surgical intervention, histopathologic analysis, treatment, and outcome of the case were examined. Results A 62-year-old man presented with a 3-month history of nasal airway obstruction, rhinorrhea, and postnasal drip refractory to medical therapy. He had a long history of exposure to fumes, chemicals, dusts, and solvents as a professional painter as well as a 45 pack-year history of smoking and alcohol abuse. The patient was ultimately found to have a left ethmoidal IP with a focus of malignant transformation into SNUC. Endoscopic resection was performed, followed by concurrent chemoradiation and adjuvant chemotherapy. After surgery, he had no evidence of recurrent disease after 9 years of follow-up. Conclusions IP is known to transform into squamous cell carcinoma. Here we report a rare case of malignant transformation into SNUC, a much more uncommon and aggressive lesion. Although traditionally associated with a poorer prognosis, the positive outcome for SNUC observed in this patient may potentially be attributed to early detection and timely therapeutic intervention.

A 50-year-old woman with a long history of nasopharyngeal cancer (T2N2M0, squamous cell carcinoma) underwent chemoradiotherapy and surgery. In the past, to prevent tumor recurrence or metastasis, she underwent concurrent chemoradiotherapy or neck dissection. However, during a follow-up 10 years after the surgery, intense F-18 fluorodeoxyglucose uptake was detected in the oral area (SUVmax 6.0). A biopsy of the area with F-18 fluorodeoxyglucose uptake revealed pathological inflammation. Radiography showed the presence of a wisdom tooth, located at the F-18 fluorodeoxyglucose accumulation site, and pericoronitis of this tooth was detected. Our findings indicate the importance of considering the effect of inflammatory conditions, such as periodontal disease, in using F-18 fluorodeoxyglucose positron emission tomography/computed tomography during follow-up after head and neck cancer treatment.

Introduction: Pilonidal disease is a chronic inflammatory process resulting from impaction of natal cleft hair into the subcutaneous tissues creating an abscess or a draining sinus over the sacrococcygeal area. Malignant transformation occurs in around 0.1%, mainly into squamous cell carcinoma (SCC) type. Wide excision with tumor-free margins remains the treatment of choice. Multiple closure techniques were settled and the best one ought to be chosen in a context malignancy and future radiological treatment. Case Presentation: We describe the management of a case of a 69-year-old male with chronic pilonidal disease, recurrent after 25 years found on final pathology to undergo malignant transformation into SCC. Wide and aggressive excision were performed with new margins and with periosteal excision of the sacrum and coccyx. rotational myocutaneous gluteal flap was done for closure of the wound in order to ensure better satisfactory esthetic results without a delay in future treatment. Conclusion: The progression of a chronic pilonidal disease into SCC is a rare but serious complication. The diagnosis is confirmed by biopsies. Workup for metastasis should be made before aggressive surgical excision. Oncoplastic surgeries is recommended for satisfactory results. Routine follow-up postoperatively should be considered due to high rate of recurrence by physical examination and imaging.

Basaloid Squamous

A 71-year-old man presented to our otolaryngology clinic with dysphagia and dyspnoea. He had a history of smoking for 40 years. Laryngoscopy showed an exophytic, round mass on the left aryepiglottic fold that was entirely excised by transoral laser CO2 microsurgery. Histological assessment revealed a pT1 basaloid squamous cell carcinoma (BSCC) with free-margin resection. He underwent close follow-up and after 3-year follow-up, the patient was free from disease. Laryngeal BSCC is a rare cancer with poor prognosis due to its late diagnosis and early neck node metastases. We report a rare case of early tumour treated by endoscopic surgery without complications or recurrence of disease. However, knowing this type of cancer and making a correct differential diagnosis are important to guarantee the best therapy and prognosis.

A five-year-old, entire female Arabian horse with a 6-month history of a non-painful nodule on the conjunctiva of the right eye was evaluated. Ophthalmological examination showed a firm, smooth and fleshy conjunctival mass that raised the suspicion of a conjunctival neoplasm. Histological evaluations showed that the mass was composed of an endophytic growth consisting of numerous long papillary projections of hyperplastic stratified squamous epithelium supported by thin fibrovascular stalks. Typical features of squamous cell carcinoma with disorganized cell growth and infiltration of surrounding tissues were detectable within the mass. Inverted papilloma progressing to carcinoma was diagnosed. Follow-up examination showed that no local recurrence was present during the 12-month follow-up period. To the authors’ knowledge, this is the first report describing the inverted papilloma in the horse and, due to its progression to squamous cell carcinoma, warns about the inclusion of the inverted papilloma in the differential diagnosis of conjunctival neoplasm and driven treatments.

Mortality And Morbidity

<p class="abstract">Sino-nasal neoplasms account for 3% of all head and neck cancers. Adenocarcinoma of the paranasal sinuses accounts for 9% of all sino-nasal malignancies and is the most common malignancy of the ethmoid sinus. Other neoplasms which involve the ethmoidal sinuses include inverted papilloma and squamous cell carcinoma. Traditionally, the treatment of choice for an adenocarcinoma of the ethmoidal sinuses involved craniofacial resection. This procedure is related with high rates of mortality and morbidity. Knegt et al reported greater success, both in terms of clinical outcome and survival data, with a less aggressive surgical approach coupled with repeated topical 5 fluorouracil (5FU) applications as a chemotherapeutic agent. Over the last 10 years we have treated selected cases of sinonasal neoplasia with a protocol similar to Knegt. Two (adenocarcinoma and inverted papilloma) of our four cases remain well and are on follow-up. The other two (undifferentiated carcinoma) were lost to follow-up. The rarity of sino-nasal neoplasms make them an unlikely subject for a randomised control trial. With that in mind surgical debridement and topical 5 fluorouracil seems to offer an acceptable treatment for adenocarcinoma of the sinonasal tract in properly selected cases. It may also have a role in Squamous cell carcinoma of ethmoidal or maxillary sinus and in preventing recurrence of inverted papilloma.</p>

<p>Verrucous carcinoma is an uncommon, locally invasive and slow growing squamous cell carcinoma of the skin and mucous membrane. The proposed causative agent for verrucous carcinoma is human papillomavirus (HPV). It has low metastatic potential compared to squamous cell carcinoma. This is a report of a 75-year-old male admitted with history of growth over the forefoot. Histopathological examinations confirmed verrucous carcinoma and the patient underwent forefoot amputation with 2 cm clear surgical margin. During the 4th month of follow-up, the patient developed a lesion at the post-operative site which was proven as a recurrence. Even though it carried low metastatic potential, it needed repeated resection or amputation because of high local recurrence.</p><p> </p>

An 8-year-old male pug with a 12-month history of a progressive nonpainful mass on the left cornea was evaluated. Ocular examination showed a severe bilateral keratoconjunctivitis sicca, pigmentary keratitis, and an exophytic irregular pink mass occupying approximately 75% of the total corneal surface of the left eye. A squamous cell carcinoma (SCC) was suspected on cytology, and clinical investigations showed no evidence of metastases. A transpalpebral enucleation was therefore performed, and the diagnosis of SCC was confirmed on histopathology. Immunohistochemical investigations showed that the neoplastic cells were pan-cytokeratin positive and vimentin negative. Additionally, nuclei immunoreactive to Ki-67 antigen were detected. Tumor cells were also negative to p53. Immunoreactivity to COX-2 was found in less than 10% of the neoplastic cells. No adjuvant therapies were instituted, and no evidence of local recurrence or distance metastasis was identified during the 24-month follow-up period.
