Analysis of related factors between the occurrence of secondary epidermoid cyst of penis and circumcision.

Secondary epidermoid cyst of the penis is a very rare epidermoid cyst that occurs in the penis. The purpose of this study was to investigate the relationship between the occurrence of secondary epidermoid cyst of penis and circumcision-related factors, and to provide possible reasonable and effective suggestions for circumcision. The data of all patients who visited the clinic for epidermoid cysts of the penis from September 2000 to September 2021 in Xiangya Hospital were collected. A retrospective study was carried out on whether the patients had been circumcised and the surgical method, anesthesia method, cyst location, surgical age, postoperative wound infection, whether they were phimosis patients, and the level of the surgeon. Among the 24 patients followed up, 95.8% had a history of circumcision, and only 4.2% had no history of circumcision, and the more traumatic surgical methods developed secondary epidermoid cyst of the penis after surgery the higher the probability. Injecting anesthesia at the base of the penis increases the chances of developing a secondary epidermoid cyst of the penis. Postoperative secondary epidermoid cyst of the penis were mainly located in the anterior segment and posterior segment, and the anterior segment had a higher proportion, followed by the posterior segment. Secondary epidermoid cyst of the penis occur mainly in adults. Postoperative wound infection accelerates the appearance of secondary epidermoid cyst of the penis. Patients with phimosis have an increased probability of developing secondary epidermoid cysts of the penis after surgery. The incidence of secondary epidermoid cysts and postoperative infection after manual circumcision by the attending physician was higher than that of the chief physician. Circumcision, injection of anesthesia at the base of the penis, ligation of the penis, and postoperative wound infection may be the etiologies and triggers of secondary epidermoid cysts of the penis. Adults and phimosis patients may be high-risk groups. Lower-level surgeons may increase the odds of postoperative secondary epidermoid cysts of the penis, and it is recommended that surgery be performed by a clinically-experienced, higher-level surgeon. The indications for circumcision should be strictly evaluated and the operation should be performed as soon as possible, and the less invasive surgical method and anesthesia method should be selected. Reduce irrelevant operations during surgery and avoid wound infection after surgery.

Quiste epidermoide en vallécula glosoepiglótica. Reporte de casos / Epidermoid cyst in the glossoepiglottic vallecula: case report

Resumen Los quistes laríngeos son muy infrecuentes y en su mayoría de etiología benigna. Se reportan dos casos de pacientes adultos que presentaron lesiones quísticas en vallécula glosoepiglótica con diagnóstico histológico de quiste epidermoide. Los quistes epidermoides en vallécula pocas veces han sido reportados en la literatura, pueden ser asintomáticos o por su localización producir síntomas como sensación de ocupación faríngea, tos o incluso dificultad respiratoria.

Abstract Laryngeal cysts are very infrequent and mostly benign. Two cases are presented of adult patients who presented cystic lesions in the glossoepiglottic vallecula with histological diagnosis of epidermoid cyst. Epidermoid cysts in vallecula have rarely been reported in the literature, they can be asymptomatic or due to their location produce symptoms such as pharyngeal occupation sensation, cough or even respiratory difficulty.

Development of Multiple Epidermal Inclusion Cysts After Radiofrequency Microtenotomy for Plantar Fasciitis: A Case Report.

Epidermal inclusion cysts are slowly developing intradermal lesions which form after the implantation of epidermal tissue into the dermal tissue. Epidermal cysts occur infrequently in the foot, but can occur after traumatic episodes, including surgically induced trauma. Epidermal inclusion cysts have been described as a complication of minimally invasive foot and ankle surgery; however, they have been described infrequently as a complication of radiofrequency microtenotomy. To our knowledge, only one other case study exists discussing the development of a singular epidermal cyst after undergoing radiofrequency microtenotomy. Therefore, the purpose of the present case report was to discuss a case of the development of multiple epidermal inclusion cysts of the plantar heel after radiofrequency microtenotomy for treatment of plantar fasciitis. After undergoing radiofrequency coblation in November 2017, the patient developed multiple plantar heel cysts. She went on to have them surgically removed in February 2018 and again in June 2018. By the time of presentation to our office in October 2018, multiple cysts were still present to her heel despite 2 surgical excisions. Seventeen months after surgical excision in February 2019, the patient remained cyst-free.

Epidermoid cyst of the anterior clinoid process: report of a unique finding and literature review of the middle cranial fossa locations.

BACKGROUND: Epidermoids cysts are relatively rare, benign, congenital tumours, representing from 0.3% to 1.8% of all intracranial lesions. When extradural, they are most commonly reported in the temporal or parietal bones as intradiploic lesions; when intradural their most common location is the cerebellopontine angle and less frequently the middle cranial fossa. Herein we present a unique case of an extradural-intraosseous epidermoid cyst of the anterior clinoid process, integrating our single-case experience into a focused literature review of these lesions, when located in the middle cranial fossa. CASE DESCRIPTION: A 49 years old man came to our attention with history of head trauma. Urgent brain CT and elective brain MRI showed imaging suggestive for an anterior clinoid process epidermoid cyst. Through a pterional approach, the lesion was completely removed with microsurgical endoscope assisted technique. MRI at one year follow up showed no recurrence. METHODS: Current literature on epidermoid cysts located in middle cranial fossa was reviewed. A total of 22 papers, containing 70 epidermoid cyst were selected for the review. Symptoms at presentation; anatomic location; surgical approach; extent of resection and recurrence; outcome after surgery and at follow up were analysed for each case. CONCLUSIONS: In the 70 published cases of middle fossa epidermoid cysts, the majority presented with trigeminal neuralgia. Most of the cases were operated through a pterional approach, while recent literature showed an increasing interest in endonasal endoscopic techniques. Subtotal resection is not a straight predictive value for recurrence; post-operative neurological deficits incidence is low and generally resolve at follow-up.

Epidermal Inclusion Cyst Formation After Barbed Thread Lifting.

Barbed thread lifting is a widely used method because it is easier to learn, faster, and the lower frequency of complications than the invasive lifting technique. The number of reported cases about complication requiring an invasive procedure is very small, and most cases are limited to minor complications. The authors introduce a chronic, recurrent epidermal inclusion cyst that occurs after Barbed thread lifting. A 61-year-old woman visited the hospital with recurrent inflammation and scar accompanied by discharge in the temporal area lasting 2 years. She had barbed thread lifting in the area of inflammation 4 years ago. CT images showed soft tissue infiltration invading superficial fascia. intraoperative view, A multi directional barbed thread was anchored in the scar tissue. The barbed thread was pulled out and cut off inflammatory lesions, including scarring wounds, were totally excised. Histopathological examination confirmed the epidermal inclusion cyst and polydioxanone suture. After surgery, the patient recovered without any complications. In this case, the cause of epidermoid cyst is considered iatrogenic concerning history of barbed thread lifting.

Epidermoid Cyst of the Lumbar Spine After Lumbar Puncture: A Clinical, Radiographic, and Pathologic Correlation.

BACKGROUND: Epidermoid cysts can rarely arise as a late complication of lumbar puncture. We describe a young man who had a remote history of a lumbar puncture and who was subsequently found to have a lumbar spinal epidermoid cyst on imaging, after presenting with lower extremity radicular pain. CASE DESCRIPTION: A 24-year-old man with a remote history of lumbar puncture presented with lower back pain and radicular leg pain which had been ongoing for over a year. Despite conservative management, the patient's symptoms progressed to worsening back pain and left L4 radiculopathy. Magnetic resonance imaging of the lumbar spine demonstrated a peripherally enhancing, intradural, extramedullary lesion at L4-5. Diffusion-weighted imaging revealed diffusion restriction within the lesion, characteristic of an epidermoid cyst. The patient underwent an L4-5 laminectomy for resection of the intradural tumor. The lesion was noted to contain pearly white granules consistent with the appearance of an epidermoid cyst. Histopathology confirmed the diagnosis. On follow-up examination, the patient demonstrated improvement of his back pain and resolution of radicular symptoms. CONCLUSIONS: Lumbar spinal epidermoid cysts may be either congenital or secondary to an iatrogenic cause. This patient had a remote history of lumbar puncture during workup for meningitis as a child. As a complication of a lumbar puncture, the formation of an epidermoid cyst can occur and is thought to be the result of implanted cutaneous tissue. This case provides a comprehensive illustration of the clinical, radiographic, intraoperative, and pathologic findings consistent with an iatrogenic epidermoid cyst.

Stüve-Wiedemann syndrome with multiple eruptive vellus hair cysts and clefted tongue.

Stüve-Wiedemann syndrome is a rare autosomal recessive congenital primary skeletal dysplasia, characterized by small stature, bowed long bones, joint restrictions, hyperthermic episodes, dysautonomia, and respiratory and feeding difficulties, that usually leads to early mortality. Cutaneous manifestations have rarely been reported. We report the case of a girl with Stüve-Wiedemann syndrome presenting with progressive development of multiple eruptive vellus hair cysts.

Iatrogenic Epidermoid Cyst of the Cauda Equina: A Late Complication of Lumbar Disc Herniation Surgery.

BACKGROUND: Epidermoid cysts (ECs) account for 0.5% to 1% of all spinal tumors. They can be congenital or acquired. Acquired spinal ECs are extremely rare and are mostly caused by trauma, or secondary to iatrogenic procedure such as lumbar punctures or surgery for spina bifida. As far as we know, this is the first report of a spinal EC complicating surgery for a lumbar disc herniation. CASE DESCRIPTION: A 69-year-old woman, with a history of L3-L4 lumbar disc herniation surgery 30 years earlier, presented because of low back pain, weakness of her lower limbs, and bladder dysfunction evolving for 2 years. Magnetic resonance imaging identified an intradural cystic lesion extending from the medullary cone to the L4 level, evoking an EC. The diagnosis was confirmed peroperatively. Neurologic motor signs improved postoperatively but not the sphincter disorders. CONCLUSIONS: Despite the extreme rarity of this event, we should be aware of the potential de novo development of epidermoid tumors in patients who undergo surgery for lumbar disc herniation. Concerns must be given to persistent low back pain and delayed neurologic symptoms in these patients.

Intraspinal Inclusion Tumor After Myelomeningocele Repair: A Long-Term Single-Center Experience.

OBJECTIVE: Given the lack of significant responses to many queries regarding behavior, treatment options, and possible prevention of iatrogenic intraspinal inclusion tumors (IITs), we think that further clinical, radiologic, and follow-up data are mandatory to better characterize this entity. We retrospectively reviewed a series of 14 consecutive patients with IIT occurring after myelomeningocele repair. The long follow-up is a mainstay of this series and may help a better understanding of the history of this slow-growing disease. To date, this is the largest series of IITs after myelomeningocele repair reported in the literature. METHODS: A retrospective chart review was performed to identify all cases of surgically repaired myelomeningocele at the Department of Neurosurgery of G. Gaslini Children's Hospital in Genoa, from January 1993 to January 2018. Among them, data regarding patients in whom an IIT developed were recovered. The medical records of these patients and their clinical history, neurologic examination, and diagnostic workup were reviewed. RESULTS: From January 1993 to January 2018, 160 cases of myelomeningocele were surgically treated. Among them, 14 cases of IIT developed. The mean time between myelomeningocele repair and IIT diagnosis was 94.7 months. The mean follow-up time was 60.1 months. CONCLUSIONS: It is well established that IITs may be discovered in patients who have previously undergone myelomeningocele repair. In our series, with a long follow-up time, we describe the possible range of behavior of such lesions and the utility of surgical treatment of primary therapy. Our series confirms that residual IITs showed marked stability during our long follow-up.

An epidermal cyst of the penis after distal hypospadias surgery: a case report.

BACKGROUND: Epidermoid cyst is a benign tumor that can occur anywhere in the body but is rarely seen in the penis. Congenital and previous penile surgeries have been reported to be involved in the etiology of the disease, which is usually asymptomatic. Here we describe a case of a patient with a penile epidermoid cyst, which occurred in the circumcision line on the left side of his penis, and urethral dehiscence following hypospadias surgery. A 3-year-old white boy who underwent primary distal hypospadias surgery 1.5 years ago presented with a slowly growing mass in the left ventrolateral portion of the penile circumcision line and urethral dehiscence. The histology of the excised mass revealed an epidermal inclusion cyst. Since then, he has remained healthy. CONCLUSIONS: Epidermal inclusion cyst as a complication of hypospadias surgery is a very rare situation. The diagnosis is made histologically and surgical excision is sufficient for treatment.

The largest epidermal cyst with vitiligo lesions following female genital mutilation: a case report and literature review.

Epidermoid vulvar cystic lesions are proliferations of epidermal cells that can occur as a complication of female genital mutilation (FGM), which is still a common practice in many cultures, especially in Africa. A 36-year-old Sudanese woman presented with an enlarged clitoral mass that had first appeared 2 years earlier. Her medical history showed that she had undergone FGM when she was 3 years old. A perineal examination revealed a mobile, nontender, rounded cystic swelling with vitiligo lesions. After the cyst was excised, it revealed a 13 ×11 × 11 cm unilocular round mass. An epidermoid cyst was reported following microscopy. Follow-up 6 months later revealed a good result with no recurrence. To date, this is the largest epidermoid cyst following FGM and the first one with vitiligo lesions reported in the literature.

Quiste epidérmico iatrogénico en región parotídea: una complicación inusual tras cirugía otológica / Iatrogenic epidermal cyst in the parotid region: a rare complication of otologic surgery

Los quistes epidérmicos son lesiones frecuentes en la piel, sin embargo, su presencia dentro de las glándulas salivares es rara, como reflejan los pocos casos encontrados en la literatura. El origen es la implantación iatrogénica de tejido epitelial en la glándula y deben considerarse en el diagnóstico diferencial cuando un paciente presenta una tumoración en esta zona con un antecedente quirúrgico otológico previo. Presentamos el caso clínico de una mujer intervenida por lesión parotídea con diagnóstico anatomopatológico de quiste epidermoide intraparotídeo. Entre sus antecedentes personales, había sido intervenida de timpanoplastia ipsilateral en la infancia, considerando que fue esta la causa de la lesión. Destacamos la rareza de la presentación de la lesión, la consideración de los quistes epidérmicos como complicación de la cirugía otológica, aunque sea infrecuente, y su importancia en el diagnóstico diferencial de las lesiones tumorales de parótida

Epidermal cysts are common skin lesions, however the presence of epidermal cysts within the salivary glands is rare as well as reflect the few cases reported in the literature. Its origin is the iatrogenic implantation of epithelial tissue in the gland and it should be considered as a differential diagnosis when a patient presents a tumor in the parotid region with previous history of otologic surgery. We report a case of a woman operated of a parotid lesion with histopathological diagnosis of intraparotid epidermoid cyst. In her personal clinical history, she has been operated for ipsilateral tympanoplasty in childhood, being considered this the cause of the lesion. Our aim is to emphasize the rarity of the presentation of the pathology, the consideration of epidermal cysts as a complication in otologic surgery, although uncommon, and its importance as a differential diagnosis in tumor lesions of the parotid gland

Management of epidermal cysts arising from scar tissues: A retrospective clinical study.

Few reports have described epidermal cysts (ECs) arising from scar tissues, and the standard course of treatment has not been established. We aimed to report the findings of a Korean patient series with ECs arising from scar tissues, to describe patient management in the context of previous publications, and to present a simple algorithm for managing ECs arising from scar tissues.We managed 6 patients with ECs arising from scar tissues, and retrospectively reviewed their demographic and clinical data.The scars were located on the anterior chest wall (n = 3), shoulder (n = 1), forehead (n = 1), and ear lobule (n = 1). Two patients with anterior chest wall scars, 1 with a shoulder scar, and 1 with an ear lobule scar had keloid scars, whereas the other patients had hypertrophic scars. The scar sizes ranged from 2 × 1 cm to 9 × 7 cm. The EC sizes ranged from 0.2 × 0.2 cm to 2 × 1.5 cm. Three patients underwent total scar revisions with complete EC excisions, 2 underwent partial scar tissue excisions with complete EC excisions, and 1 had laser therapy for the scar and EC. No complications occurred, and all patients' final outcomes were satisfactory during the mean follow-up period of 14.8 months.We successfully managed the patients with ECs arising from scar tissues. We recommend that surgeons and patients first decide whether the ECs and scar tissue should be completely removed. Moreover, consideration should be given to the options chosen for the management of ECs. Finally, postoperative scar care is necessary to prevent hypertrophic and keloid scar recurrences.

Surgical management of a huge post-circumcision epidermoid cyst of the vulva presenting unusually in a postmenopausal woman: a case report.

BACKGROUND: Epidermoid cysts of the external genitalia are one of the late complications of female genital mutilation. These cysts are usually small and painless. The presentation of a giant vulvar cyst in a postmenopausal woman has not been reported; the surgical management of a large cyst is often challenging. CASE PRESENTATION: A 60-year-old, para VI, Ethiopian woman presented with an 18 cm by 12 cm sized, fluctuant, multi-lobulated, mobile, non-tender vulvar mass involving the mons pubis. She had undergone genital cutting and sewing during her childhood. Informed consent was obtained for surgery and the vulvar cyst was excised successfully without any significant bleeding or injury to the adjacent structures. Her postoperative course was smooth and histopathology confirmed epidermoid cyst of the vulva. CONCLUSIONS: Huge epidermoid vulvar cysts following genital mutilation are rare and presentation in a postmenopausal woman has not been reported. Practitioners in areas where female genital mutilation is prevalent should be aware of the peculiar anatomic and technical aspects of the surgical removal of these giant vulvar cysts for successful therapeutic and cosmetic outcomes.

Traumatic Epidermal Inclusion Cyst After Minimally Invasive Surgery of a Displaced Intra-Articular Calcaneal Fracture: A Case Report.

Epidermal inclusion cysts are common epithelial cysts of the skin. The latter classically originate from progressive cystic ectasia of the infundibular portion of hair follicle. Therefore, these cysts are usually found in hairy regions and rarely in glabrous skin such as the palms and soles. The etiology of glabrous epidermal inclusion cysts appear to be different from that of those located in hairy regions. It has been suggested that implantation of epithelial cells into subcutaneous tissue, such as during trauma, is most likely the pathophysiologic basis. Epidermal inclusion cysts on the palms and soles are often misdiagnosed, leading to improper treatment. Therefore, we report a rare case of an epidermal inclusion cyst of the heel after minimally invasive surgery of a displaced intra-articular calcaneal fracture.
