Abstract: Basosquamous carcinoma (BSCC) is a rare type of skin cancer with an incidence of less than 2% of all skin cancers and the risk of local recurrence ranges between 15% and 50%. We reported a male, aged 57 years old, working as a civil employee, came to the eye clinic with a recurrent BSCC in the right lower palpebral since a month ago. The patient was previously diagnosed as BSCC and had undergone a surgery to remove cancer cells in 2017. However, in 2019, a scan of the axial incision of the head revealed a tumor mass in the right infraorbital area with T4N0Mx. The hypodense structured tumor mass showed increased contrasting. The opera-tive management performed was extensive excision and deep excision with rotational flaps and drainage attached. Histopathological examination of the tumor tissue and excision margins, optic nerve tissue, as well as infraorbital bone tissue indicated a BSCC. Diagnosis of BSCC was confirmed based on anamnesis, physical examination, ophthalmic examination, head CT scan with contrast, and histopathological examination. This case report was aimed to explore BSCC especially in palpebra due to the lack of data of similar cases as well as the potential for diagnosis and promising management.Keywords: basosquamous carcinoma (BSCC), palpebral, reccurent  Abstrak: Karsinoma basoskuamosa (BSCC) merupakan jenis kanker kulit yang langka dengan kejadian kurang dari 2% dari semua jenis kanker kulit namun dengan risiko kekambuhan lokal berkisar 15% dan 50%. Kami melaporkan kasus seorang laki-laki berusia 57 tahun, bekerja sebagai ASN, datang ke klinik mata dengan BSCC palpebra kanan bawah berulang sejak satu bulan lalu. Pasien sebelumnya didiagnosis dengan BSCC dan telah menjalani operasi untuk mengangkat sel kanker pada tahun 2017. Namun, pada tahun 2019, pemindaian kepala sayatan aksial menunjukkan adanya massa tumor di area infraorbital kanan dengan T4N0Mx. Massa tumor berstruktur hipodens dengan kontras yang meningkat. Manajemen operatif dilakukan eksisi ekstensif dan eksisi dalam dengan flap rotasi dan drainase terpasang. Pemeriksaan histopatologik dilakukan terhadap jaringan tumor dan margin eksisi, jaringan saraf optik, serta jaringan tulang infraorbital dengan simpulan suatu BSCC. Pada kasus ini diagnosis BSCC ditegakkan berdasarkan anamnesis, pemeriksaan fisik, pemeriksaan oftalmologi, pemeriksaan penunjang berupa CT scan kepala dengan kontras, dan pemeriksaan histopatologik. Laporan kasus ini bertujuan untuk mendalami BSCC khususnya di palpebra karena minimnya data mengenai kasus yang serupa, serta potensi diagnosis dan penatalaksanaan yang menjanjikannya.Kata kunci: karsinoma basoskuamosa (BSCC), palpebra, rekuren

Background: CT Scan provides the biggest contribution in receiving radiation doses in patients. Especially in pediatric patients or children. Local DRL (Diagnostic Reference Level) is an effort to optimize radiation for patients in every health facility. During this time the LDRL value is determined from the CTDIvol displayed from the CT Scan workstation. However, CTDI has a weakness which is irrelevant for wide-beam CT and is only a tool output dose, not paying attention to patient size. SSDE is a dose correction based on the patient's geometry. Purpose: This study aims to determine the estimation of pediatric patient dose profiles on head CT scan based on SSDE values to determine LDRL. Methods: The study was conducted by collecting data on pediatric patient doses with an age range of 0-1 years, 2-5 years and 6-10 years who underwent a head CT scan within the period from July to December 2017. The samples were measured lateral and anterior-posterior diameter for determine the correction factor. The results of the CTDIvol record and conversion factor will determine the SSDE value. The third quartile data from SSDE is specified as LDRL. The SSDE value in the three groups shows the same trend which is smaller than the CTDIvol value. The correction of the factor  gives estimates of doses received by patients reduced by 2.6%, 8.5% and 20% respectively for ages 0-1 years, 2-5 years and 6-10. Acceptance of patient doses is influenced by tube tension, filament current, rotation time, scan length, number of phases and pitch. Conclusion: From the results of the SSDE value, DRL values can be determined for the age group 0-1 years, 2-5 years and 6-10 years respectively 23,1±1,5 mGy, 24,3± 1,8 mGy and 27, 5± 10,5mGy.
