Eccrine Poroma

<p>Eccrine poroma is a benign adnexal tumor arising from cells of the outer layer of the acrosyringium and upper dermal eccrine duct. It generally appears as a solitary, slow growing, sessile, pink-to-red and well-circumscribed papule, plaque or nodule. It is usually located on the palms and soles but it may also develop on other locations. Its clinical appearance can resemble other types of tumors such as hypo- or amelanotic melanoma. Dermoscopy has  improved the evaluation of skin tumors. In the case of eccrine poroma, there are some studies that have described its dermoscopic findings. These mainly focus on its vascular structures. We present an 82-year-old patient who developed a 2×3-cm eccrine poroma on his lower back. Dermoscopy demonstrated the presence of a polymorphous vascular pattern displaying mostly linear looped (irregular hairpin-like) and “leaf-flower-like” vessels (“cherry-blossom” and “chalice-like”), with some resembling “cactus-like” structures. Only a few linear coiled (glomerular) and linear helical (corkscrew) vessels were observed. Some of these vascular structures were surrounded by a whitish-to-pink halo. Moreover, some pink structureless areas were present. We highlight the finding of the “leaf-flower-like” vessels, as these are vascular structures that have not been described in other types of skin tumors.</p>

Eccrine Poroma

Eccrine poroma is a rare benign adnexal neoplasm originating from a portion of the intraepidermal eccrine sweat gland duct and the acrosyringium. Typically, the lesions are asymptomatic, slow-growing nodules, which may be found in any sweat gland–bearing area. Multiple red lacunae, glomerular vessels, hairpin vessels, flower- and leaf-like vascular patterns, a polymorphic vascular pattern, globule/lacunae–like structures, a frog egg–like appearance, and comedo-like openings have been defined as characteristic dermoscopic patterns of the disease. We report a case of eccrine poroma in an unusual periungual and subungual location mimicking ingrown toenails. The dermoscopic findings of the lesions were compatible with those of eccrine poromas located in areas other than the periungual area. Recurrence was observed after the first excisional biopsy. There was no recurrence 10 months after the second surgical intervention, and near-complete regrowth of the nail plate was achieved. Eccrine poroma should be considered as a differential diagnosis in the presence of slow-growing, erythematous, painful, hemorrhagic papular lesions located in the periungual area in conjunction with a prediagnosis of ingrown toenails and malignant processes.

Adnexal Tumor

A case of 15year old female presented with lesion over back since childhood, with occasional bleeding and oozing from lesion without any associated systemic complaints. There were multiple verrucous coalescing papules forming plaque with overlying erosion present over left lower back- diagnosed provisionally as angiokeratoma circumscriptum and was biopsied. Histopathology revealed findings consistent with Syringocystadenoma papilliferum. Surgical excision was done and closed with rotation flap. Syringocystadenoma is benign cutaneous adnexal tumor presenting clinically with many morphologies such as warty papules, nodules, plaques with oozing of serous material. Lesion is usually seen in head and neck area in most cases however can also occur on extremities, buttocks, anogenital region. It is characterized by multiple invaginations from skin surface in association with hair follicles lined by cuboidal to columnar epithelium on luminal aspect and myoepithelial cells on outside. There is papillary architecture and dermal ductal component.

Eccrine Poroma

Pyogenic granulomas are benign vascular tumors characterized histologically by a lobular proliferation of capillaries. We report an unusual presentation of a pyogenic granuloma in an elderly patient with a bleeding red nodule on the plantar surface of the foot. Nodular exophytic plantar foot lesions often present a diagnostic challenge, as the differential diagnosis includes benign and malignant entities ranging from eccrine poroma and pyogenic granuloma to Kaposi's sarcoma and amelanotic melanoma. This case highlights the need for an adequate biopsy technique to confirm the diagnosis and guide management.

Albino patients are at great risk for developing cutaneous neoplasms, including melanomas. In this paper we describe the dermatoscopic findings of nevi in two patients with oculocutaneous albinism type Ia (OCA-Ia) highlighting that they manifest a vascular pattern similar to that described for amelanotic melanoma. We propose managing these patients with dermoscopy, using the comparative approach, digital follow up (DFU), and reflectance confocal microscopy as a complementary tool for difficult cases.

Glomus jugulare is a rare slow growing tumor occurring within the jugular foramen that rarely presents with isolated symptoms. Although histologically benign, these tumors are locally destructive because of their proximity to the petrous bone, the lower cranial nerves, and the major vascular structures (Miller et al. (2009) and Silverstone (1973)). We wish to report a glomus jugulare tumor eroding the petrous bone and producing an ipsilateral peripheral facial weakness. The mechanism of this erosion is discussed.

Kista dentigerus merupakan kista yang berhubungan dengan gigi yang tidak erupsi berasal dari sisa epitelial organ pembentuk gigi. Gejala klinis menunjukkan pembengkakan yang tumbuh lambat dan tidak sakit pada rahang. Gambaran radiografis memperlihatkan area radiolusen uniokular yang mengelilingi mahkota gigi yang tidak erupsi. Proses infeksi kronis pada kista dentigerus dapat menyebar lambat membentuk abses subperiosteal dan melewati barrier kulit membentuk fistel ekstra oral. Studi kasus ini laporkan seorang wanita 56 tahun yang datang ke poli Bedah Mulut dan Maksilofasial RSUP Dr Sardjito dengan kasus kista dentigerus pada regio angulus mandibula kanan dengan fistel ekstra oral pada pipi kanan. Penatalaksanaan kasus adalah pemberian antibiotik, enukleasi kista, pengambilan gigi 45, 47 dan 48 yang impaksi sertafistulektomi dengan pendekatan ekstra oral dan sinus shoe polishing technique di bawah bius umum. Evaluasi 3 minggu pasca operasi menunjukkan penyembuhan ekstra oral dan intra oral sempurna serta tidak terbentuk jaringan parut. ABSTRACT: Management of Infected Dentigerous Cyst with Extra Oral Fistulae on Right Cheek. Dentigerous cyst is an odontogenic cyst associated with unerupted teeth from epithelial remnant teeth organ. The clinical appearance shows slow-growing painless swelling lesion in jaw. The radiografics reveals uniocular radiolucency surrounding unerupted teeth. The chronic infection proccess in dentigerous cyst could spread slowly forming subperiosteal abcess and, through cutaneous barrier, it forms extra oral fistulae. We reported a 56 year old woman who came to RSUP Dr Sardjito with dentigerous cyst in mandible angulus with extra oral fistulae in the right cheek. The treatment consisted of antibiotic medication; cyst enucleation; removal of unerupted third molar, second premolar, second molar; and fistulectomy with extra oral approach and sinus shoe polishing technique under general anesthetic. Three week evaluation post surgery shows succesful extra oral and intra oral healing without scarring.
