Specific applications: Radiofrequency commonality
Published in Bipin Deshpande, Dermatologic Surgery with Radiofrequency, 2018
Sebaceous cysts are quite commonly seen in practice. Being harmless, patients usually do not bother to treat them unless infected. These are commonly seen on the scalp, face, neck, chest, and back. They can be removed by two methods explained next. See Figures 13.46 to 13.49.

This is the classic presentation of a sebaceous cyst. Sebaceous cysts arise due to proliferation of epidermal cells within the dermis. They are common, typically solitary, firm and slow-growing, and they are found on the face, trunk, neck and scalp. The presence of a central punctum is pathonemonic. Keratoacanthomas are classically dome-shaped and firm, with a central keratin-filled crater. They typically occur in sun-exposed areas, and they often grow rapidly and spontaneously resolve.Ganglions are benign cystic swellings that arise from a joint or tendon sheath. The description of the lump is not consistent with either a lipoma or malignant melanoma.

This benign cyst is usually found on the skin of the labia majora or minora. The appearance is similar to a sebaceous cyst. The cyst may be asymptomatic but can also become infected. The management is the same as for a sebaceous cyst.

A 16-month-old male with no past medical history presented to the outpatient Otolaryngology-Head and Neck Surgery office with a midline cutaneous neck mass. The mass had been present since birth and was slowly increasing in size. This mass was painless and was never infected. Pertinent negatives included the absence of dysphagia, dyspnea, hoarseness and noisy breathing. On physical examination there was a 3 mm × 2 mm pedunculated, subcutaneous mass slightly superior to the sternal notch in the midline. No sinus tract was palpable and there was no cervical lymphadenopathy. Due to the superficial nature of this mass, laboratory testing was not felt to be necessary. The differential diagnosis for this patient included bronchogenic cyst, thyroglossal duct cyst, dermoid cyst, abscess, sebaceous cyst, and a variety of skin neoplasms.

Dermoid cysts usually present as firm facial subcutaneous swellings in infant [1]. Although these lesions are congenital, most of them are not diagnosed at birth but between 14 and 34 months of age [1,2]. Studies on gender predilection show contradictory results. Some report an equal sex distribution, Pollard et al. found a female predominance and Bradley et al., Rahbar et al. and Denoyelle et al. reported a male predominance [3,4]. The incidence of nasal midline dermoid cysts is one in 20,000–40,000 births. Dermoid cysts are derivatives from both ectoderm and mesoderm, differentiating them from other common cystic tumors like sebaceous cysts, ganglion cysts, epidermoid cysts and tricholemmal cysts [1–5]. The cysts are lined by stratified squamous epithelium [1–3,5,6]. The most common area of presentation is the head and neck region, with the lateral third of the orbit being the most frequently affected area [1,3]. Dermoid cysts in the nasal midline are rare and can be found anywhere from the columella up to the glabella. 3.7–12.6% of head and neck dermoids are on the nose, representing 1–3% of all dermoids [3–5,7]. In children, they account for 61% of all midline nasal lesions [5,7].
Non–small cell lung cancer presenting as back cyst

A 60-year-old female smoker presented to her primary care physician with a new painful back cyst. Ultrasound showed a 2.5 cm subcutaneous mass. She was diagnosed with an infected sebaceous cyst and prescribed oral antibiotics. Despite antibiotics, the back cyst continued to grow, and her pain increased. The cyst was excised, and biopsy showed a malignant epithelial tumor with mucinous differentiation. Staging computed tomography (CT) scans of the chest discovered a cystic mass in the subcutaneous tissues, mediastinal lymphadenopathy, and a 2.2 × 1.9 cm spiculated mass in the right upper lobe of the lung (Figure 1a, 1b). By the time of her initial oncology visit, she had developed complete blindness in the left eye and was admitted to the hospital for further care.
