Sebaceous carcinoma of the eyelid is a very rare slow-growing tumor and is considered an aggressive eyelid neoplasm. It can reach mortality rate of about 6%. Diagnosis is often delayed because of its ability to masquerade as other periocular lesions, both clinically and histologically. We present three cases of sebaceous carcinoma, with different surgical outcomes, showing the importance of early diagnosis.

Carcinoma sebáceo é um tumor raro de crescimento lento considerado uma das mais agressivas neoplasias palpebrais. Pode alcançar taxa de mortalidade de aproximadamente 6%. O diagnóstico tardio é comum devido a sua habilidade de se confundir com outras lesões perioculares tanto clinicamente quanto histologicamente. Relatamos três casos de carcinoma sebáceo da pálpebra com diferentes resultados cirúrgicos, enfatizando a importância do diagnóstico precoce.

Sebaceous carcinoma (SC) of the eyelid is a rare slow-growing tumor that affects the elderly men and women(1), arising from meibomian, Zeis or sebaceous glands in the caruncle, eyebrow or surrounding skin. SC accounts for approximately 0.2% to 0.8% of all eyelid tumors and 1.0% to 5.5% of all eyelid malignancies(2).
Diagnosis is often delayed because of its ability to masquerade as other periocular lesions, both clinically (chronic blefaroconjunctivitis and recurrent chalazion) and histologically, mainly basal cell carcinoma (BCC) and squamous cell carcinoma (SCC)(3). The most common method of metastasis of eyelid SC is through the lymphatic channels to regional lymph nodes and it may reach mortality rate of 6% due to metastasis(3). Conservative surgery may be tried for treatment of localized SC, however aggressive procedures are frequently performed due to delaying in the diagnosis(4,5).
We present three cases of SC, with different surgical outcomes, showing the importance of early diagnosis.
A 73 year-old woman presented with 1-year history of an elevated slow growing lesion in the left upper eyelid. She smoked for 35 years, and referred chronic solar exposure. On examination, a chalazion-like 5-mm nodular lesion with localized madarosis was noted on eyelid margin (Figure 1A). Eversion of the eyelid displayed real size of the lesion (7x9 mm), involving approximately 50% of the tarsus (Figure 1B). No lymph nodes were detected. An incisional biopsy was performed and the histopathology revealed an SC infiltrating the tarsus. The patient underwent surgical excision with intraoperative frozen section. Three millimeters of healthy-appearing tissue excision was enough to achieved tumor free-margins. Direct closure eyelid reconstruction was performed using Tenzel procedure(6). The patient had good functional, anatomical and esthetic outcomes. The 15-day postoperative aspect is showed in figure 1C. At 12 months of follow-up, there was no evidence of recurrence or metastasis.
A 58-year-old man developed a nodular lesion in the right upper eyelid with telangiectasia, local madarosis and ulcerated center (Figure 2A), clinically diagnosed and surgically treated as chalazion, two years ago. The patient had no information about previous histological analysis. No lymph nodes were found. He had systemic hypertension, tobacco use for 40 years and chronic solar exposure. Everting the tarsus, the lesion displayed greater proportions, compromising more than 60% of the eyelid (Figure 2B). This patient underwent surgical excision of the visible tumor with 3-mm of healthy-appearing margin in all directions. Intraoperative frozen analysis showed a superior compromising and an additional 2-mm resection was performed. Due to size of defect, it was necessary eyelid reconstruction using hard palate graft for the posterior lamella and sliding skin and muscle flap for the anterior lamella(6). Histological analysis confirmed the diagnosis of SC with clear margins. The patient evolved with upper eyelid retraction (Figure 2C) and a transient keratitis and has opted for no further surgical procedures. At one-year follow-up, there was no evidence of recurrence or metastasis.
A 71-year-old man was referred for chronic left eyelid and eye inflammation, beginning 5 years ago, diagnosed and treated as chronic blefaroconjunctivitis in several services. He presented to us complaining about progressive clinical worsening and low visual acuity for 1 year. He referred hypertension. His visual acuity was 20/25 OD and 20/50 OS. Left biomicroscopy evaluation showed a thickened and hyperemic superior eyelid, with viscous discharge and generalized cilia loss, associated with important and diffuse conjunctival hyperemia, superficial corneal opacity and 360º limbal neovascularization (Figure 3A). No lymph nodes were detected. Multiple conjunctival map biopsies were performed including left upper and lower eyelid tarsus, superior and inferior cul-de-sac, four quadrant bulbar conjunctiva and the cornea epithelium. All specimens were compromised by SC with pagetoid spread. A magnetic resonance imaging showed signs of orbital fatty infiltration without bone involvement. Clinical systemic evaluation placed the patient in T4N0M0 stage. Orbital exenteration was performed. Patient has been followed for 3 years, without signs of metastasis or recurrence.
These three patients with SC alert the importance of the early diagnosis in the final surgical outcome. The first case had a medium lesion diagnosed in an early time point. It allowed relatively simple surgical treatment with good functional and esthetic outcome. The misdiagnosis of chalazion in the case 2 compromised the surgical prognosis. It was necessary to perform a more aggressive surgery and the patient developed eyelid retraction, but it was still possible to preserve the visual function. In case 3, unfortunately, the misdiagnosis and late detection of the disease leaded the patient to a regrettable mutilating operation, recommended for this kind of pagetoid spread(4).
The diagnosis of SC can often be difficult both clinically and histopathologically(3,5). As reminded case 2, any tissue surgical removed must always be sent to histopathological evaluation, even if it seems a benign lesion, as a chalazion(4).
The histopathology of SC is dominated by large anaplastic cells with open vesicular nuclei and prominent nucleoli set in foamy or frothy cytoplasm (lipid vacuoles). It is advisable to alert the pathologist to the possible diagnosis and ask for the preferred method of tissue handling(7). When the histopathological result disagrees with the clinical suspicion, it is recommended thorough lamina revision(8). This pathology is very rare(2) and, probably, it is not uncommon that experienced pathologists are in front of their first SC case.
Blepharoconjunctivitis is other common clinical misdiagnoses of SC, especially in the spreading superficial clinical presentation, like seen in case 3. Dragging or recurrent cases of blepharoconjunctivitis are strong candidates for cytology impression or even biopsy, depending on clinical features(8). Nodular SC is easier to be perceived both by patients and by physicians compared with the spreading SC. It probably also contributed to late diagnosis and worse prognosis of case 3. The majority of SC cases affect the upper eyelid(2), probably due to the greater concentration of meibomian glands in this region. BCC and SCC, on the other hand, usually involve the lower lid(2). Thus, it has been suggested that any clinically malignant lesion of the upper lid should be considered SC until proven otherwise(4).
Upper eyelids SC tend to metastasize to preauricular and parotid nodes, which represent the most common sites of metastasis. Tumors of the lower eyelid can metastasize to submandibular and cervical nodes. Death from metastasis can reach 6% of cases(3).
Thus, patient should be referred to an oncologist for properly systemic evaluation and follow-up, even after a successful free margin surgery. There is no specific follow-up guideline for SC in the literature. Given the rarity of SC of the eyelid, surveillance recommendations would require a thorough literature review of this topic and discussion among groups of experts. A series of 3 cases is not enough to support this, but due to similar metastizing pattern, the guideline for melanoma follow-up(9) could probably be appropriated. It includes follow-up visit every 3 months until 2 years have passed from the diagnosis. Thereafter, follow-up is continued every 6 months for 5 years.
SC first metastasizes into regional lymph nodes, which should be followed-up carefully by palpation. Recently, it was demonstrated that sentinel node analysis may be also helpful to detect subclinical metastasis in SC, but the false-negative rate is higher than that reported for sentinel node biopsy at most other anatomic sites(10). If the clinical examination in these follow-ups suggests tumor spreading, a chest x-ray, blood count, liver function tests, and liver ultrasonography should be performed(9). Muir-Torre syndrome should be also remembered and multidisciplinary investigation is also recommended(1).
Even with this suggested melanoma guideline follow-up, some rhetoric questions like "What is the basis for recommending ultrasound rather than CT scans, since ultrasound may miss metastatic disease?", "Based on the sites of metastases, why would imaging of the brain not be done?", "What treatment would be available for treatment of metastatic disease detected with surveillance imaging?" and "Is there evidence that early detection improves survival?" show us the necessity of developing surveillance guidelines for SC of the eyelid and other skin areas.
