Porokeratosis ptychotropica: a rare case report with unusual presentation

Porokeratosis is a rare disorder of epidermal keratinization characterized clinically by annular plaque with thread like hyperkeratotic border with a central groove that expand centrifugally and this border corresponds to coronoid lamellae histologically which are the columns of parakeratosis that overlie an epidermal invagination with loss of granular layer and dyskeratosis of upper spinous keratinocytes. The disorder was erroneously named porokeratosis because the coronoid lamella was initially described as being present over a sweat pore, which is a fixed structure that cannot expand peripherally. Five primary clinical variants have been described: classic porokeratosis of mibelli, disseminated superficial actinic porokeratosis, linear porokeratosis, punctate porokeratosis and porokeratosis palmaris et plantaris disseminate. Porokeratosis ptychotropica one of the rare variants of porokeratosis described by lucker et al which has been added recently in the classification. It is characterized clinically by symmetrical verrucous papules and plaques resembling psoriasis plaque in the gluteal cleft, buttocks and rarely extends to genitalia and histologically by multiple coronoid lamella. We report a case of 43year old female, presented with 10years duration of pruritic raised skin lesion over the left gluteal region. Dermatological examination revealed single well defined erythematous scaly plaque with central atrophy, hyperpigmentation and peripheral thread like elevated border. Histopathological examination revealed multiple coronoid lamella which is the hallmark for porokeratosis ptychotropica, confirmed the diagnosis. The patient was treated with 5-fluorouracil cream. we report this case due to its rarity and the unusual presentation of single plaque of porokeratosis ptychotropica.

ABSTRACT The trichoepithelioma is a benign cutaneous neoplasm which is derived from hair follicles. It is common in the face, but there are only three reports of the solitary occurrence on the nose. It is often not recognized because of its rarity, controversial classification, origin and biological potential. The objective of this paper is to present a case of solitary trichoepithelioma on the nose, histopathological examination and treatment. It should be considered as a differential diagnosis of a solitary lesion of nose which is confused with basal cell carcinoma. The confirmation by histopathological examination is essential.

Cervical melanosis is a rare entity in the spectrum of melanocytic lesions of uterine cervix. Melanosis is defined as presence of melanocytes in the basal layer of squamous epithelium causing hyperpigmentation. Authors here by report a case of 57-year-old female who underwent vaginal hysterectomy for third degree utero-vaginal prolapse, showed an incidental gross pathological finding of brownish macular lesion. Histopathological examination showed hyperpigmentation of basal layer without increase in melanocytes. On immunohistochemical examination, basal melanocytes were highlighted by S-100 and HMB 45 immunostains. Thus final diagnosis of cervical melanosis was made. Clinical differentials of cervical pigmented melanocytic lesions include cervical melanomas, blue nevi, congenital or traumatic lesions and melanosis, hence vigilant clinical, gross pathological examination and biopsy is warranted.

ABSTRACTHuman coenurosis is a rare zoonotic disease caused by the larvae of Tinea multiceps seen in sheep-rearing countries. We report the case of a 63-year-old male who was referred to our hospital with a working diagnosis of skull base chondrosarcoma. Histopathological examination after surgical excision revealed characteristic feature of coenurus with multiple scolices invaginating from the outer cuticular layer. Coenuri are often mistaken for giant cysticercal cysts and hydatid cysts. Despite its wide prevalence in cattle, only two cases of human coenurosis are reported from India till date. We report the third case from India.

Wall Tumor

AbstractPrimary Dirofilariasis is caused by a Zoonotic filarial nematode. It is transmitted to humans by Culex, Aedes, or Anopheles mosquitoes, which ingest blood-containing microfilaria from affected dogs, cats, or raccoons. Chest wall tumors are uncommon lesions that originate from blood vessels, nerves, bone, cartilage, or fat. We report a case of Human Dirofilariasis due to D. Repens occurring in the chest wall in a 32 year old male. Clinical diagnosis of benign chest wall tumor was considered and it was excised. Histopathological examination confirmed it as Dirofilaria repens. On regular follow up he is doing fine.

Dorsal Spinal

ABSTRACTEpidermoid cysts are commonly seen intracranial lesions but their occurrence in the spine is rare. They account for <1% of all the benign tumors of the spine. These are benign epithelial-lined cysts filled with keratin. They are classified into two types: congenital or acquired. Congenital epidermoid cysts are more commonly associated with spinal dysraphic states such as syringomyelia, dermal sinus and spina bifida whereas the acquired cysts are associated with repeated lumbar punctures. Based on the location, they can be extradural, intradural, extramedullary, or intramedullary. Most of the epidermoids are intradural extramedullary. Intramedullary epidermoid cysts are very uncommon. We report a case of a 6-year-old female patient with dorsal epidermoid cyst with neurological deficits. Magnetic resonance imaging of the spine showed a well-defined lesion from D9 to D12 which was hypointense on T1W1 and heterogeneously hyperintense on T2W2. Surgery was performed to excise the lesion and to decompress the spinal cord. Histopathological examination of the excised lesion confirmed it as an epidermoid cyst.

Rare Case Report

Micropapillary carcinoma is an uncommon variant of urothelial carcinoma with high metastatic potential. Usually seen in elderly individual, we herein report a case of 42 years old man presented with macroscopic hematuria for 1 month. Evaluation with CECT whole abdomen revealed irregularly marginated hyperattenuated mildly enhancing intraluminal mass lesions in right lateral wall and in floor of urinary bladder. No perivesical infiltration and no regional lymphadenopathy were detected. TURBT done and subsequent histopathological examination showed a high-grade transitional cell carcinoma with micropapillary variant. He was subjected to radical cystoprostatectomy with pelvic lymph node dissection. The pathological examination revealed a high-grade transitional cell carcinoma with micropapillary variant invading the perivesical adipose tissue. No tumor recurrence or metastasis was reported at the 18-months follow-up.
