A 70-year-old man complained of the sensation of having a foreign body in his left eye in June 1992. A papillary tumor was found growing from the palpebral conjunctiva of the left upper eyelid. On June 30, the conjunctival tumor was excised: the histopathologic findings indicated a malignancy. On August 18, full-thickness excision of the upper eyelid, including the rest of the tumor, was performed. Histopathologic findings showed a well-differentiated sebaceous gland carcinoma. We believe that sebaceous gland carcinoma presenting as conjunctival papilloma, as found in our patient, may be uncommon.

Objectives: This work highlights the methods used to develop a multi-pulse 1726 nm laser system combined with bulk air-cooling for selective sebaceous gland (SG) photothermolysis using thermal imaging and software algorithms. This approach enables treating to a desired tissue temperature and depth to provide a safe, effective, reproducible, and durable treatment of acne.
Methods: We designed and built a 1726 nm laser system with a 40 W maximum power output, a highly controlled air-cooling device, and a thermal camera in the handpiece, which permits real-time temperature monitoring of the epidermis.
Acne vulgaris affects approximately 80% of young adults and adolescents in the world. Acne presents as comedones, pustules, papules, and nodules on the face, chest, shoulders, or back. It can lead to a significant decrease in quality of life with a high risk of associated depression and anxiety.

Sebaceous carcinoma is a rare cutaneous malignancy of sebaceous glands, but it is up to 25-fold more common in immunosuppressed individuals. In this narrative review, we examine the current literature on the pathogenesis, incidence, risk factors, prognosis, treatment, and surveillance of sebaceous carcinoma in immunosuppression and highlight practical considerations for providers who care for these patients. Increased incidence may be related to decreased immune surveillance, susceptibility to an unknown viral trigger, microsatellite instability, immunosuppressive medications, and unmasking of occult Muir-Torre Syndrome.

Background: Seborrheic dermatitis (SD) is a chronic, inflammatory disease characterized by unknown etiopathogenesis. It affects skin areas rich in sebaceous glands. There are strong data on the relationship between nutrition habits, body mass index (BMI), psychoemotional status, and sebaceous gland diseases such as acne, rosacea, and androgenetic alopecia.

To develop an atrophic Meibomian Gland Dysfunction (MGD) animal model via liquid nitrogen cryotherapy, the eyelid edges of C57 mice exposure to liquid nitrogen for 30 s. Morphology of MG and ocular surface were assessed using stereomicroscopy and a slit lamp microscope at multiple time points post-injury. Acinar loss and atrophy were observed from day 7, with increased inflammation and apoptosis, and decreased proliferation in acinar cells.
