1/16. Eruptive vellus hair cyst in a patient with pachyonychia congenita.pachyonychia congenita is characterized by symmetrical nail dystrophy, palmoplantar keratoderma, oral leukokeratosis, and follicular hyperkeratosis. In addition to these features, multiple cutaneous cysts of various kinds have been described. We report a case of pachyonychia congenita associated with eruptive vellus hair cyst.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
2/16. Multiple epidermal inclusion cysts in a patient with rheumatoid arthritis: a case report.A construction worker with rheumatoid arthritis presented with multiple soft tissue masses on the volar surface of the palm and digits. A misdiagnosis of rheumatoid nodules was made secondary to the patient's history of rheumatoid arthritis. Subsequent excision confirmed multiple epidermal inclusion cysts, which was not entertained in the preoperative differential diagnosis. Follow-up evaluation 3 years later revealed no evidence of local recurrence. Based on our literature review, multiple epidermal inclusion cysts is a rare entity and has not been reported in a patient with rheumatoid arthritis.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
3/16. Eruptive vellus hair cyst and epidermoid cyst in a patient with pachyonychia congenita.We report the first case of pachyonychia congenita (PC) associated with both eruptive vellus hair cyst (EVHC) and epidermoid cyst. The patient is a 12-year-old Japanese girl who presented with two natal teeth at birth. She had thickening and discoloration of the fingernails and toenails, plantar hyperkeratosis, palmar-plantar hyperhidrosis and multiple cutaneous cysts. Histologic examination revealed EVHC and epidermoid cyst.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
4/16. Posttraumatic epidermal inclusion cyst of the deep infratemporal fossa.The authors report a case of an epidermal inclusion cyst found in the deep infratemporal fossa 12 years after the patient sustained blunt trauma to that region. Posttraumatic epidermal inclusion cysts are rare and occur mainly in the fingers, palms, and soles. Introduction of the epidermal elements into the dermis during the trauma is thought to be the cause. This case is rare in presentation, with few reports in the English literature that describe an epidermal inclusion cyst in the deep infratemporal fossa. review of the English literature disclosed no other cases of epidermal inclusion cyst after blunt trauma involving the deep infratemporal region.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
5/16. Giant epidermoid cyst on the forefoot.BACKGROUND: Epidermoid cysts are the most common cysts of the skin, usually appearing in the hairy regions. However, epidermoid cysts on the non-hair-bearing areas, such as the palms and the soles, are rare and seldom reach a size of more than 5 cm in diameter. OBJECTIVE: To present a patient with an epidermoid cyst of unusual location and size. methods: A 23-year-old woman with a painless tumorlike mass on her right forefoot was examined and the mass was excised. RESULTS: The 6.5 cm x 5.5 cm x 5.5 cm mass was totally excised. Histologic diagnosis was reported as an epidermoid cyst. CONCLUSION: An original case regarding an unusual location and size of an epidermoid cyst is presented.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
6/16. Multiple palmar epidermoid cysts.Implantation of epidermal fragments into the dermis has been pointed out as the cause of common epidermal cysts. However, some palmoplantar epidermoid cysts have been reported to be caused by human papillomavirus (HPV) infection or to be derived from eccrine ducts. A 65-year-old left-handed woman presented with extraordinary multiple epidermoid cysts on the palm and volar aspect of the fingers of her left hand. HPV infection was not detected by immunohistochemistry, in situ hybridization and polymerase chain reaction. Histological investigation revealed syringeal structures within the cyst wall and in the cyst cavity. carcinoembryonic antigen was observed in these syringeal structures but was not specifically stained in the cyst wall cells by immunohistochemistry. The cytokeratin composition of the cyst wall cells was similar to that of the nonadnexal epidermis.- - - - - - - - - - ranking = 6keywords = palm (Clic here for more details about this article) |
7/16. Human papillomavirus-associated plantar epidermoid cyst related to epidermoid metaplasia of the eccrine duct epithelium: a combined histological, immunohistochemical, dna-dna in situ hybridization and three-dimensional reconstruction analysis.BACKGROUND: We recently proposed that certain palmoplantar epidermoid cysts may be related to eccrine ducts and that human papillomavirus (HPV) 60 may play a role in their pathomechanism. However, the origin of palmoplantar epidermoid cysts is still controversial. OBJECTIVES: To examine the contribution of eccrine ducts and HPV 60 in the development of epidermoid cysts. methods: Five epidermoid cysts and four ridged warts that had developed on the soles of a patient were studied histologically, immunohistochemically and by dna-dna in situ hybridization. Using serial sections obtained from its entire body, a three-dimensional reconstruction (3DR) analysis was performed on the smallest cyst to analyse the relationship between the epidermoid cyst, eccrine duct and the overlying epidermis. RESULTS: Histological and dna-dna in situ hybridization analyses demonstrated both homogeneous intracytoplasmic inclusion bodies pathognomonic for HPV 60 infection and HPV 60 dna sequences not only in all of the epidermoid cysts and ridged warts but also in the acrosyringeal portion of an eccrine duct, with the dermal portion of which the smallest cyst had been revealed to connect by 3DR analysis. However, immunohistochemical analyses using antibodies against human carcinoembryonic antigen (CEA), involucrin and several cytokeratins (CKs) revealed that the immunoreactivity of the cyst was not identical to that of the eccrine dermal duct but was identical to that of suprabasal layers of the epidermis. CONCLUSIONS: It was clearly demonstrated that an HPV 60-associated epidermoid cyst with immunoreactivities for CEA, involucrin and CKs which were identical to those of the epidermis connected with the eccrine dermal duct, supporting the idea that certain palmoplantar epidermoid cysts may develop following the epidermoid metaplasia of eccrine ducts with HPV 60 infection.- - - - - - - - - - ranking = 3keywords = palm (Clic here for more details about this article) |
8/16. natal teeth and steatocystoma multiplex: a newly recognized syndrome.A Chinese family is reported in which five generations have exhibited natal teeth and generalized multiple steatocystomas. This autosomal dominant condition is not similar to the two reported types of pachyonychia congenita, because nail lesions, palmoplantar keratosis and hyperhidrosis, follicular keratosis, and oral leukokeratosis were not observed. Therefore, it is suggested that this family exhibits a newly recognized syndrome.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
9/16. Palmoplantar milia: sequelae of early congenital syphilis.A 5-month-old male was examined in our dermatology clinic with numerous palmoplantar milia. The child had early congenital syphilis with palmoplantar desquamation, which was followed by the development of milia. Histologic and electron microscopic features suggested that these secondary milia probably derived from the epidermis.- - - - - - - - - - ranking = 2keywords = palm (Clic here for more details about this article) |
10/16. pachyonychia congenita Jackson-Lawler type: a distinct malformation syndrome.A family with three members in two generations affected by pachyonychia congenita, hyperkeratosis and hyperhidrosis of the palms and soles, follicular keratosis, neonatal teeth and epidermoid cysts (Jackson-Lawler syndrome) is described. The nosological autonomy of this condition is proposed and a further heterogeneity is suggested on the basis of histopathological changes in the subcutaneous cysts.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
