INTRODUCTION: Cutaneous appendageal tumor can differentiate towards or arise from either pilosebaceous apparatus or the eccrine sweat glands. Appendageal tumors are relatively rare, their clinical appearance is non-specific, and the vast majority are not diagnosed until after excision. Eccrine porocarcinoma (EP), also known as malignant eccrine poroma is a rare adnexal tumor arising from the intraepithelial ductal parts of the sweat gland. CASE PRESENTATION: We presented a 65-year-old, Asian, female with medical co-morbids, who came with both a facial squamous cell carcinoma and a long-standing lesion over her left forearm...

Tumor thickness is the strongest predictor of outcome for clinically localized melanoma. Therefore, accurate assessment is critical for appropriate staging, reliable estimation of prognosis, and management. When melanoma extends alongside skin adnexal structures more deeply than the main tumor mass (periadnexal extension), it is currently unknown whether the prognosis is more accurately reflected by the deepest point of periadnexal tumor extension or the main tumor mass. This study sought to address this question...

Aims: To assess whether replacing CA125 with HE4 in the classical formulas of risk of malignancy indices (RMIs) can improve diagnostic performance. Methods: For each of 312 patients with an adnexal mass, classical RMIs 1-4 were computed based on ultrasound score, menopausal status, and serum CA125 levels. Additionally, modified RMIs (mRMIs) 1-4 were recalculated by replacing CA125 with HE4. Results: Malignant pathology was diagnosed in 52 patients (16...

Pilomatrix carcinoma is an exceedingly rare skin adnexal neoplasm derived from piliferous follicles, usually occurring in the head and neck region. Localization of this tumor in the breast is a rarity. We now report an unusual case of a 49-year-old female who presented with a palpable mass in the left breast for 2 years. Mammogram revealed a large, lobulated opacity with calcification, and positron emission tomography-computed tomography showed a metabolically active soft tissue mass measuring 15 cm involving all the quadrants of the left breast...

Proliferating trichilemmal tumor (PTT), still referred to as proliferative trichilemmal cyst (TC), is an uncommon malignant adnexal tumor originating from the cells of the outer root sheath of the hair follicle or, more often, from a trichilemmal cyst, following multiple trauma and/or recurrent inflammation. We report the case of a 64-year old female patient, with no particular previous history, presenting with tumor of the scalp gradually evolving over 18 months. Clinical examination showed a painless, firm, adhering ulcero-budding tumor mass measuring 12 cm along its longer axis at the level of the vertex...

Organ transplant recipients (OTRs) are a population at high risk for cutaneous adverse events. Their early recognition and appropriate treatment is an important component of the clinical management of OTRs and should be optimally dealt with by dermatologists working in the context of a transplant dermatology clinic. Skin examination should be a standard procedure before performing organ transplantation to assess conditions which may be difficult to manage after the transplant procedure has been performed or which may represent a contraindication to transplantation, e...

Clear cell renal cell carcinomas (CCRCC) rarely metastasizes to the gynecologic tract. In this study, we analyzed a multi-institutional data set to provide insights into the clinical, morphologic, and immunophenotypic features of this phenomenon. Seveteen metastatic CCRCC involving the gynecologic tract [ovary/fallopian tube (n=9), vulva (n=2), uterine corpus (n=3), cervix (n=2), uterine serosa (n=1)] were analyzed. Mean patient age was 62 yr (range: 45-79 yr). Most cases (15/17) presented as a recurrence 6 to 72 mo postnephrectomy, 1 case was concurrently diagnosed, and 1 case (a cervical metastasis) was diagnosed prenephrectomy...

Adnexal masses in pregnancy are not commonly encountered. The majority of these masses are discovered incidentally during routine follow-up. However, some of these masses become symptomatic due to their size, location, and impingement of adjacent structures. Several diagnostic modalities can be utilized for the detection of adnexal masses with different sensitivity and specificity rates. The differential diagnosis of adnexal masses discovered during pregnancy is broad and includes both benign and malignant lesions...

Eccrine porocarcinoma is a rare, malignant adnexal tumor of the duct of eccrine sweat gland. Cytology of eccrine porocarcinoma has been described in very few previous literature. Here, we present a case of fine needle aspiration cytology (FNAC) of eccrine porocarcinoma of the scalp, which is subsequently confirmed by histology. Accurate diagnosis of eccrine porocarcinoma by FNAC is very difficult, but determining the malignant nature of the lesion is crucial for curative surgery. FNAC can be a convenient, safe, and effective approach to solve difficult diagnostic dilemma...

Periocular neoplasia is common in horses. Treatment of the periocular skin and ocular adnexal structures can be technically challenging. Common neoplastic conditions, a treatment algorithm, surgical principles, and therapeutic modalities are reviewed. Regardless of the type of neoplasia found or the treatment that is applied, success is most likely when the neoplastic tumor is small.

Melanocytic matricoma is a recently described cutaneous adnexal tumor composed of matrical and supramatrical cells admixed with pigmented dendritic melanocytes, thought to recapitulate the anagen bulb of the hair follicle. We report a case of a 75-year-old white man, which demonstrates consumption of the epidermis that is defined as thinning of the epidermis with attenuation of the basal and suprabasal layers and loss of the normal rete architecture in areas of direct contact with neoplastic cells. It has been associated with aggressive histologic features in melanoma and likely represents an early phase of ulceration due to attenuation...
