BACKGROUND: Multiple miliary osteoma cutis of the face represents primary extra-skeletal bone formation that arises within the skin of the face. METHODS: A 60-year-old woman with multiple miliary osteoma cutis of the face was treated by application of 0.05% tretinoin (all-trans-retinoic acid) cream nightly. RESULTS: After 3 months of therapy there were fewer papules and a decrease in size of remaining lesions. In a literature search, it was found that local application of tretinoin was successful and achieved a decrease in the number of papules over the face in all patients with multiple miliary osteoma cutis of the face; however, the length of time to achieve response varied from a few weeks to 6 months. CONCLUSION: It is suggested that local application of tretinoin cream should be considered in the therapy of multiple miliary osteoma cutis of the face, particularly when the lesions are small and superficial.

Rhabdoid meningioma is an aggressive phenotype of meningioma, associated with a poor prognosis. We present a very rare case of high-grade meningioma with rhabdoid features that eventually expressed in a coma state. Comprehensive genomic profiling using a Next Generation Sequencing (NGS) assay revealed three genomic alterations: activating BRAF mutation (V600E), loss of CDKN2A/2B, and APC I1307K. After treatment with BRAF inhibitor (dabrafenib), the child's clinical condition improved progressively. After seven months, an MEK inhibitor was added (trametinib). [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to identify risk factors for incomplete excision of squamous cell carcinomas (SCCs). Patients and methods: A cross-sectional study of 369 patients who underwent a primary excision of SCCs was performed within an outpatient and a hospital plastic surgery department setting. Results: Incomplete excision occurred in 25 of 369 primary excisions of SCC (6.8%). Location of the tumors on the forehead, temples, peri-auricular region, ears, cheeks, nose, lips or neck was significantly associated with incomplete excision of the tumors. In particular, high incomplete excision proportions were observed for tumors located on the ears (16.7%), neck (16.7%), temples (11.1%), nose (10.8%) or lips (7.1%). Incomplete excision of SCC was associated with the setting of the operation in the hospital as compared to ambulatory settings ( p = 0.046) and was inversely associated with the specimen thickness ( p = 0.002). There was no statistically significant association between incomplete excision of SCC and gender, age, clinical appearance of the lesion (suspected SCC vs other diagnoses), differentiation pattern, diameter of the tumor, length or width of the excised specimen, solar changes or ulceration. Conclusion: We recommend that in patients with SCCs located in the forehead, temples, periauricular region, ears, cheeks, nose, lips or neck surgeons should commence particular surgical measures to avoid inadequate excisions of the tumors. In particular, surgeons should use wider excisional margins in tumors located in the embryonic fusion planes (e.g. eyelids and naso-labial folds). [ABSTRACT FROM AUTHOR]
