Pilomatrix Carcinoma

Malignant of pilomatrixoma, known as pilomatrix carcinoma, is a rare cutaneous adnexal tumor that derives from hair matrix cells.The tumor usually occurs in male, with the predominant age range between 40 to 60 years old, located in the head and neck area. The tumor consisted of atypical basaloid cells aggregation, ghost cells, and keratinous material. We report a case of 54 years old male patient referred to Cipto Mangunkusumo Hospital Jakarta with a mass in his right upper quadrant abdomen and a lump in the axilla. The magnitude resonance imaging (MRI) and positron emission tomography (PET)-scan revealed metastatic lesions in several lymph nodes and internal organs. The patient underwent liver biopsy which showed that tumor was composed of atypical basaloid cells, amyloid-like material, keratin mass, and was diagnosed as pilomatrix carcinoma. This case is being reported due to its rarity, potential pitfalls due to histologic similarity with several other entities, and to show the importance of histopathology examination in patient’s treatment to prevent a devastating outcome.

Uncommon Tumor

Abstract Nodular hidradenoma is an uncommon cutaneous adnexal tumor arising from sweat glands. In the skin, it usually presents as a solitary dermal nodule; excision is curative in most cases. In rare instances, it may present as a breast mass and can mimic breast carcinoma clinically and radiologically, causing diagnostic dilemmas for the treating physician and pathologist. Herein, we discuss a case of nodular hidradenoma in a 20-year-old Hispanic woman as a rapidly growing mass in the breast that mimicked breast carcinoma. We discuss the rare presentation of this uncommon tumor and the differential diagnosis of this entity, as well as the results of our literature review on the topic.

Pilomatrix Carcinoma

This is the first report of pilomatrix carcinoma in a man with C282Y myotonic dystrophy type 1. This pilomatrix carcinoma had originally presented as a rapidly growing recurrence of a histopathologically confirmed pilomatrixoma, removed a year prior. On examination, the fungating mass had measured 10 × 23 cm. A wide local resection with removal of suspicious lymph nodes was preformed, and the resulting defect was reconstructed with a latissimus dorsi myocutaneous flap and skin graft. Histologic investigation of the excised mass confirmed the diagnosis of pilomatrix carcinoma. This is the first reported case of pilomatrix carcinoma in a patient with a genetic condition that often presents with scalp pilomatrixomas. Potential implications of myotonic dystrophy on developing pilomatrix carcinoma are discussed.

Background: Pilomatricoma is a common benign adnexal tumor differentiating toward elements of the hair matrix and shaft. It typically presents as a solitary, deep, dermal nodule. We describe a case of a pilomatricoma with the unusual feature of a thick-walled dermal bulla overlying the tumor. Objective: We describe a case of bullous pilomatricoma and discuss the potential etiology of the bullous feature of the lesion. Methods: This article includes a case report and a literature review. Conclusions: Bullous pilomatricoma has rarely been described. A common pathological feature in this type of pilomatricoma is the presence of dilated lymphatics. Bullous morphea associated with dermal lymphatic dilation has also been described. In both bullous pilomatricoma and morphea, it is possible that individual pathological features of the lesion lead to obstruction and congestion of the dermal lymphatics thereby inducing enough dilation and edema to form a dermal bulla. Antécédents: Le pilomatrixome (épithéliome calcifiant de Malherbe) est une tumeur annexielle bénigne qui ressemble aux éléments de la matrice et de la tige pilaires. Il se manifeste typiquement par un nodule sous-cutané solitaire. Nous rapportons un cas de pilomatrixome présentant la caractéristique inhabituelle d'une bulle dermique à paroi épaisse située au-dessus de la tumeur. Objectifs: Décrire un cas de pilomatrixome bulleux et présenter l'étiologie potentielle d'une telle manifestation. Méthodes: Cet article comporte une étude de cas ainsi qu'une revue de la littérature. Conclusion: Le pilomatrixome bulleux a rarement été décrit. La dilatation des vaisseaux lymphatiques constitue une manifestation pathologique fréquente de cette forme de pilomatrixome. La morphée bulleuse a également été associée à une dilatation de vaisseaux lymphatiques. Il est possible que les caractéristiques pathologiques individuelles des lésions du pilomatrixome bulleux et de la morphée entraînent une obstruction et une congestion des vaisseaux lymphatiques, provoquant ainsi une dilatation et un œdème suffisamment importants pour former une bulle.

Malignant Proliferating Trichilemmal Tumor

Proliferating trichilemmal tumors (PTTs) are neoplasms derived from the outer root sheath of the hair follicle. These tumors, which commonly affect the scalp of elderly women, rarely demonstrate malignant transformation. Although invasion of the tumors into neighboring tissues and being accompanied with anaplasia and necrosis are accepted as findings of malignancy, histological features may not always be sufficient to identify these tumors. The clinical behavior of the tumor may be incompatible with its histological characteristics. Squamous-cell carcinoma should certainly be considered in differential diagnosis because of its similarity in morphological appearance with PTT. Immunostaining for CD34, P53, and Ki-67 is a useful adjuvant diagnostic method that can be used in differential diagnosis aside from morphological findings. In this study, we aimed to present the case of a 52-year-old female patient with clinicopathological features. We reported a low-grade malignant proliferating trichilemmal tumor in this patient and detected no relapse or metastasis in a 24-month period of follow-up.

Sebaceous adenocarcinoma is a rare adnexal tumor that can affect the skin and is divided into ocular, a more common form and extra ocular, of a rarer occurrence. We report the case of a patient diagnosed with Acquired Immune Deficiency Syndrome (AIDS) who developed an extra ocular, bulky and fast-growing sebaceous adenocarcinoma on the face. The literature has suggested that transplanted patients and HIV-positive patients have an excess risk for developing adnexal tumors, including sebaceous adenocarcinoma.
