Ocular sebaceous carcinoma is an uncommon, aggressive ocular neoplasm with potential for regional and distant metastasis.
Case presentation
A 77-year-old woman was found to have a solitary pulmonary lesion 6 years after the initial treatment of sebaceous carcinoma of the eyelid. Video-assisted lung wedge resection of an undetermined pulmonary nodule was carried out successfully. Microscopically, the tumor showed foamy cytoplasm and atypical nuclei, consistent with metastasis of eyelid sebaceous carcinoma.
Conclusion
This is the first case report of resected solitary pulmonary metastasis of eyelid sebaceous carcinoma. Pulmonary resection is a good option for the treatment and diagnosis of metastatic eyelid sebaceous carcinoma.

Background
Sebaceous carcinoma of the eyelid is a relatively rare malignant tumor, and accounts for less than 1% of all eyelid tumors [1]. As well as being a rare tumor, sebaceous carcinoma can mimic other benign inflammatory and malignant processes, thus errors or delays in diagnosis are not unusual [2‐5]. Although local management strategies for this tumor have previously been described [6‐10], very few reports have focused on the patterns of metastasis of this tumor and the treatment strategies for such metastases [7, 8]. Here, we report a case of solitary lung metastasis of eyelid sebaceous carcinoma, and discuss the clinical implication of surgery for a solitary pulmonary metastasis from sebaceous carcinoma.
Case presentation
A 77-year-old woman underwent left upper lid resection in April 2006 for sebaceous carcinoma of the eyelid. The surgical margin was negative for cancer cells. In January 2008, she had developed a recurrence in the left upper eyelid, and underwent radiotherapy with a total dose of 57.6 Gy of proton beam therapy followed by orbital exenteration of the left eye [11, 12]. In July 2012, positron emission tomography–computed tomography (PET-CT) revealed a solitary pulmonary nodule 0.5 cm in size in the right upper lobe of the patient’s lung, which had increased to 1.1 cm by September 2013 (Figure 1A). PET-CT revealed a focus of increased uptake in that nodule, with a standardized uptake value of 3.7 (Figure 1B). There was no evidence of other metastatic disease on PET-CT scans. In September 2013, the patient underwent video-assisted thoracoscopic wedge resection of the pulmonary nodule. Frozen sections using oil red O stain revealed accentuation of lipid and presences of foamy cytoplasm in tumor cells, which was positive for lipid staining (Figure 2). Permanent histology demonstrated tumor cells with foamy cytoplasm and atypical nuclei, accompanying numerous lipid globules within the cytoplasm (Figure 3), consistent with metastasis of eyelid sebaceous carcinoma. At the last follow-up, 7 months after resection, there was no loco-regional recurrence or distant metastasis of the tumor after surgery.

Discussion
Sebaceous carcinoma of the eyelid refers to a group of carcinomas derived from sebaceous gland cells that occur in the ocular adnexa. It can be invasive in the eyelid and conjunctiva, and can metastasize to regional lymph nodes and distant organs [8, 13, 14]. Treatment strategies for primary eyelid sebaceous carcinoma are surgery, radiotherapy, and chemotherapy [15‐17]. Distant hematogenous metastases to the lung, liver, and brain have a mortality rate as high as 30% [16, 18]. However, few reports demonstrated the surgical treatment of metastatic eyelid sebaceous carcinoma.
Standard treatment strategy for pulmonary metastatic sebaceous carcinoma has not yet been established because of the limited number of cases. Chemotherapy regimens in existing reports are largely based on the combination regimens commonly used in the treatment of other forms of poorly differentiated carcinomas of the head and neck region [19, 20]. Husain et al. reported combined chemotherapy of carboplatin and docetaxel for the patient who had multiple lung and lymph node metastases, which resulted in a 30% decrease in tumor size, but the efficacy of this regimen for sebaceous carcinoma has not yet been fully evaluated [21]. Radiotherapy for primary eyelid sebaceous carcinoma was described in several reports; however, there have been no reports describing radiotherapy for pulmonary metastatic eyelid sebaceous carcinoma [22, 23]. Resection of pulmonary metastases in patients with sebaceous carcinoma is controversial. However, our case suggests that a surgical approach to lung metastasis of eyelid sebaceous carcinoma could prolong survival in certain subgroups of patients, namely, those with a limited number of metastatic nodules or a significant disease-free interval.
The possibility of metastasis from eyelid sebaceous carcinoma or primary lung cancer cannot be predicted only on the basis of radiologic findings or disease-free interval. In the present case, we could successfully differentiate solitary lung metastasis of eyelid sebaceous carcinoma from primary lung cancer using oil red O stain, which stains lipid has a red color, on frozen sections.
Conclusion
We report a rare case of solitary lung metastasis of eyelid sebaceous carcinoma, which was successfully resected and differentiated from primary lung cancer using oil red O stain on frozen sections. Pulmonary resection is a good option for the treatment and diagnosis of metastatic eyelid sebaceous carcinoma.

Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.
Das Webinar beschäftigt sich mit Fragen und Antworten zu Diagnostik und Klassifikation sowie Möglichkeiten des Ausschlusses von Zusatzverletzungen. Die Referenten erläutern, welche Frakturen konservativ behandelt werden können und wie. Das Webinar beantwortet die Frage nach aktuellen operativen Therapiekonzepten: Welcher Zugang, welches Osteosynthesematerial? Auf was muss bei der Nachbehandlung der distalen Radiusfraktur geachtet werden?
