“…EICs, also known as epidermal cysts, epidermoid cysts, sebaceous cysts, or infundibular cysts, are benign cystic lesions, which are characterized by the proliferation of epithelial cells locally in the dermal or subcutaneous tissue, leading to the formation of a keratin-filled cyst [1 , 2] . They may result from the obstruction of a pilosebaceous follicle, migration of epithelial cells during embryogenesis, or acquired reasons such as trauma or surgery [3] , [4] , [5] . Clinically, they appear as solitary slowly growing lumps with sizes ranging from a few millimeters to a few centimeters, with or without a central characteristic punctum.…”

“…[15] Five centimeter or greater cysts have been describes as "giant." [16,17] Although malignant transformation is rarely seen, the features that would help in differentiating proliferating epithelial cyst from squamous cell carcinoma include the clinical presentation of a slow-growing subepidermal cystic tumor, origin from a preexisting cyst, and lack of evidence of origin from a premalignant epidermal lesion, such as actinic keratosis or Bowen's disease. A biopsy must be undertaken to rule out malignancy.…”

IntroductIonBenign skin tumors are soft-tissue lesions that frequently present with poor cosmesis along with pain, functional limitations, deformity, and hypoesthesia depending on the location. [1] Numerous histopathological subtypes, including lipomas, epidermoid cysts, fibroepithelial polyps, neurofibromas, pilar cysts, and xanthomas have been described, ranging from 1 to 2 mm to giant dimensions. [1][2][3] The term "giant benign tumor" is usually described and categorized individually for different tumor types. Although benign skin tumors progress slowly and are usually asymptomatic, rapid progression and giant forms should be evaluated and differentiated from malignant transformation.The purpose of this study was to evaluate patients operated for giant benign skin tumors in our department and to compile noteworthy characteristics regarding each tumor subtype regarding surgical indications, size, location, and histopathological results and follow-up. MaterIals and MethodsFollowing the approval of the Clinical Studies Board of Ethics, this study included a total of 16 consecutive patients who underwent surgery for giant benign skin tumors between 2015 and 2018 based on the literature definition of "giant benign skin tumors." Written informed consent was obtained from all patients, and the study protocol was compliant with the guidelines of the Declaration of Helsinki. Demographic parameters, indications, symptoms, pathological results, and postoperative complications were evaluated retrospectively.Background/Aim: Benign skin tumors are soft-tissue lesions that present with poor cosmesis along with pain, functional limitations, deformity, and hypoesthesia. Rapid progression and giant forms should be evaluated and differentiated from malignant transformation. The aim of this study is to evaluate the patients operated for giant benign skin tumors and to assess clinical experience about indications, size, location, and histopathological results and follow-up period. Materials and Methods: The present study included 16 consecutive patients who underwent surgery for giant benign skin tumors between 2015 and 2018 based on the literature definition of "giant benign skin tumors." Demographic parameters, indications, symptoms, pathological results, and postoperative complications were evaluated retrospectively. Results: Sixteen patients (11 males and 5 females) were operated for giant benign skin tumors. The mean age of the patients was 53.38 (range: 37-72) years. Tumor locations were on the scalp for four patients, the upper extremity for three patients, lower extremity for three patients, trunk for five patients, and generalized for one patient. Pain was the most common symptom, and hypoesthesia, functional limitations, ulceration, and infection were also observed. Total excision was performed for all patients. No major complications and recurrence were observed. Conclusion: Clinical follow-up is an option for patients presenting to clinic with lesions that are small in size and asymptomatic. However, a detailed histor...

Introduction. Epidermal cysts are common benign cutaneous cysts. An epidermal cyst may be classified as a giant epidermal cyst if it exceeds 5 cm. Giant epidermal cysts with a diameter of 5 cm or more are rare but have been reported. The epidermal cyst rarely discloses malignancy. Although rare, a case of malignant change of benign epidermal cyst is possible. We describe here a rare case of a giant epidermal cyst of the parietooccipital region in a 35-year-old man. Case Illustration. A 35-year-old man was admitted to the hospital with a huge swelling over the scalp for the past 30 years. The swelling was non-tender, cystic, measuring 18x13x 9 cm, and was situated in the parietooccipital region. Skull CT revealed an oval shape, hypodense mass, well defined, in the parietooccipital scalp with no intra-cranial extension. Complete excision of the lesion was carried out. Excision of redundant skin is needed to achieve good aesthetic results. Histopathological examination showed a thin layer of benign stratified squamous epithelium and lamellated keratin debris present in the cyst. There is no sign of malignant transformation. Conclusions. It can be stated that although epidermal cyst is a slow-growing benign tumor, it can cause diagnostic difficulties when located in the scalp area and when there is a possibility that cranial bones and even intracranial structures are affected by the cyst. CT, MRI or ultrasonography are crucial to determine if the cyst contacts intracranial structures. The histopathology examination should be done to detect malignant transformation.
