Trapdoor Deformity Correction Post Nasal Bilobed Flaps for Basal Cell Carcinoma Reconstruction With Multiple Laser Modalities.

ABSTRACT: In case of excision of nasal basal cell carcinoma (BCC), bilobed flaps are considered the criterion standard of reconstruction for defect less than 15 mm in size. However, there is still a risk of trapdoor deformity formation, of which its treatment is less discussed. A 44-year-old woman who was diagnosed with nasal BCC and underwent tumor excision with bilobed flap reconstruction presented with trapdoor deformity postoperatively. The computed Vancouver Scar Scale was 7. After early intervention of multiple laser modalities, including 2 sessions of 585-nm pulsed dye laser with a fluence of 9 J/cm2, pulse duration of 6 milliseconds, and spot size of 6 mm, 2940-nm Er-yttrium aluminum garnet (YAG) laser with a pulse energy of 800-900 mJ, repetition rate of 8-9 Hz, and laser spot size of 3-7 mm, and 5 sessions of 1064-nm Nd:YAG fractional picosecond laser with a pulse energy of 2.30-2.70 mJ, repetition rate of 8 Hz, and laser spot size of 6 mm from 5 to 23 weeks postoperatively, the Vancouver Scar Scale score improved to 1, with significant reduction of trapdoor scar erythema and puffiness. Although BCC is often curable, tumor excision causes unsatisfactory appearance satisfaction problem, owing to the apparent location of the lesion. Factors, such as sebaceous tissue thickness, reconstruction over multiple aesthetic subunits of nose, and damage to nasal cartilage framework structure during tumor removal, may increase the risk of trapdoor formation. Early intervention with multiple laser treatment can significantly revise the deformity.

Concurrent aspergillosis and cystic pulmonary metastases in a patient with tongue squamous cell carcinoma.

Pulmonary Aspergillus infection may have a variety of manifestations depending on the patients' immunity status and pre-existing lung conditions. Radiographically, aspergilloma, which is usually associated with noninvasive Aspergillus fumigatus conidia, may feature a characteristic mass in a cavity commonly located in the upper lobes of the lung. It is typically encountered upon pre-existing lung damage. Here we report Aspergillus growing in a pulmonary metastatic cavity in a 47-year-old male worker with a history of tongue cancer after a radical operation with neck dissection and concurrent chemotherapy in 2014. Chest radiography and computed tomography showed a cavitary lesion with a ball-in-hole lesion in the right upper lobe (RUL) and two cystic lesions within the bilateral upper lung field. Endobronchial ultrasound-guided transbronchial biopsy (EBUS-TBB) from the RUL anterior segmental bronchus (RB3) revealed the presence of Aspergillus conidia and squamous cell carcinoma. Wedge resection of the cystic lesion within the left upper lobe confirmed the diagnosis of metastatic squamous cell carcinoma. This is a rare case of aspergillosis within cavities of pulmonary metastases in a patient who was diagnosed with tongue squamous cell carcinoma. The conclusive distinction between neoplasm and fungal infection is difficult to achieve by radiography, and a pathological biopsy by EBUS-TBB is necessary to aid diagnosis. Clinicians should be aware of such an atypical presentation of metastases coexisting with Aspergillus infection.

A rare case of synchronous multiple primary lung cancer with different responses to gefitinib.

Differentiating multiple primary lung cancer (MPLC) from lung metastasis is important, and the pathology and gene mutations may be different between the tumors. A lung biopsy to differentiate lesions should be considered, especially when the response of different tumors to treatment is distinct.
