Abstract
Microcystic adnexal carcinoma (MAC) is a rare kind of cutaneous neoplasm with a very aggressive local infiltration that destructs the affected tissues. Its rate of recurrence is high and it mostly involves the face and scalp regions and most of the patients get affected in the fourth or fifth decades of their life. Here in, we report a 61-year-old woman with a right-sided eyebrow MAC lesion with recurrency. Total excisional surgery was performed. A-T Flap surgery was applied on the involved area, and after a 2-year period of follow-up, with no recurrency, hair transplantation with follicular unit transplantation method was successfully performed on the scarred area. Although microcystic adnexal carcinoma is an uncommon neoplasm; dermatologists and ophthalmologists should consider it as a differential diagnosis, due to its aggressive local infiltration. Complete surgical excision and long-term follow-up must be applied to manage the disease. Also, hair transplantation with follicular unit transplantation technique can be considered as a beneficial method for treating scars resulted from MAC excisional surgery.

Abstract
Microcystic adnexal carcinoma (MAC) is a low-grade adnexal carcinoma with controversial lines of differentiation. We present here an example of MAC showing histopathologic findings of germinative follicular differentiation in the form of solid aggregates of trichoblastoma intermingled with neoplastic aggregates of MAC. Immunohistochemical findings, showing positivity for PHLDA1 and negativity for BerEp4 in neoplastic aggregates of trichoblastoma, also supported a germinative follicular differentiation. Follicular differentiation in MAC supports an apocrine line of differentiation for this neoplasm.

Abstract
Desmoplastic trichoepitheliomas (DTEs) are benign cutaneous neoplasms that originate from the hair follicle and exhibit a preference for the facial region. This type of neoplasm is characterized by accelerated growth, with vigorous histologic and immunohistochemical features that may be confused with other skin cancers. Thus, the objective of this study is to establish a definitive diagnosis that can be widely used. This review was systematically carried out and includes case series and studies to establish valuable data that can be used for research. The articles were sought in PubMed, MEDLINE, and Google Scholar using the keywords "desmoplastic trichoepithelioma," "morphea basal cell carcinoma," "microcystic adnexal carcinoma," "syringoma," and "cutaneous breast carcinoma." From a total of 65 journal articles, we chose 42 studies describing the clinical features, etiology, histopathology, and immunohistochemical characteristics of tumors. After quality assessment, 10 studies were selected, representing the differentiating features among the four mentioned cutaneous tumors. The differential diagnosis of DTE also includes other cutaneous and follicular tumors. At present, there is no standardized grading system for trichogenic tumors, although several symptomatic terms have been offered. More recently, immunohistochemistry and histopathological studies support the differentiation between the above-mentioned cutaneous tumors. However, additional research needs to be conducted to obtain complete information regarding the specific distinct traits of the indicated cutaneous tumors.

Abstract
AIMS Laminin (Ln)-γ 2, one of the chains of Ln-332, is a marker of invasive tumours and is frequently expressed as a monomer in malignant tumours. Desmoplastic trichoepithelioma (DTE), some types of basal cell carcinoma (BCC) (infiltrating and morphoeic BCC) and microcystic adnexal carcinoma (MAC) belong to a group of tumours known as sclerosing adnexal neoplasms (SAN) that are frequently difficult to differentiate and often require immunohistochemistry for diagnosis. The aim of this study was to assess the usefulness of Ln-γ 2 expression in the differential diagnosis of DTE, infiltrating/morphoeic BCC, MAC and syringoma. METHODS AND RESULTS In this study, we compared the expression of Ln-γ 2 in infiltrating/morphoeic BCC (n = 28), DTE (n = 26), MAC (n = 10) and syringoma (n = 20). Immunohistochemically, Ln-γ 2 positivity was noted in 96% (27 cases) of infiltrating/morphoeic BCC and 90% (nine cases) of MAC, while all DTE and syringoma cases were negative. Furthermore, Ln-γ 2 expression pattern in infiltrating/morphoeic BCC was different from that in MAC. Ln-γ 2 expression was found in the cytoplasm of tumour cells in infiltrating/morphoeic BCC tumour cells, while in MAC linear expression was noted both along tumour nests and in the cytoplasm. CONCLUSION Ln-γ 2 is a helpful adjunct in the differential diagnosis of SAN.

Abstract
BACKGROUND Solid carcinoma is a poorly characterized malignant apocrine neoplasm as only 16 cases have been published. OBJECTIVE To characterize its clinical, histopathological, and immunohistochemical features. METHODS We compiled 14 cases of solid carcinoma and clinical information were updated. Hematoxylin and eosin slides were reviewed and we stained all the cases for CEA, EMA, SMA, PHLDA-1, BerP4, nestin, p53, p63, p75, CK5/6, CK7 and some with remaining material for CK14, 15, CK10, CK19, S100, CD117, and CAM5. RESULTS All the lesions were located on the scalp. Histopathologically, all the cases were characterized by solid aggregates of neoplastic epithelial cells without nuclear atypia or mitotic figures involving all the dermis. All the cases presented perineural infiltration and most of them had cornified cystic structures. CK5/6 and p63 were positive. CEA and EMA underlined the scarce ducts. Ki67 was lower than 1%. BerEP4 and PHLDA-1 were negative. CONCLUSION Solid carcinoma is a solid variant of MAC affecting the scalp more frequently than classic MAC, mostly in old males and showing variable-sized nests involving the entire dermis and composed by poroid, clear-cells, or a mixture of both. It is positive for p63 and CK5/6 and negative for BerEP4 and PHLDA-1. Staining features with CK19 and PHLDA1 differ from classic MAC.

Abstract
Microcystic adnexal carcinoma (MAC) is a rare malignancy of sweat glands that has been reported most often on the face in the form of a cutaneous lesion, with the potential for deeper invasion. The synonyms of MAC include sclerosing sweat duct carcinoma, syringomatous carcinoma, and malignant syringoma. Clinically, MAC in the periocular area has been misdiagnosed as basal cell carcinoma, squamous cell carcinoma, or even chalazia. We report a case of MAC presenting clinically as sebaceous gland carcinoma with pagetoid spread for the first time in literature.

Abstract
Microcystic adnexal carcinoma (MAC) is extremely rare among Asians, with the majority of cases presenting in Caucasian individuals. The current study describes the case of a 38-year-old Chinese woman who presented with a 10 year history of a mass in the upper lip. A biopsy resulted in a diagnosis of MAC. The patient underwent complete surgical resection and the tumor was successfully excised. During 6 months of follow-up, there was no evidence of recurrence. To the best of our knowledge, the present case is the first Chinese case to be reported in the English literature, and is presented with the aim of increasing the awareness and aiding in the management of MAC in non-Caucasian populations.

Abstract
Desmoplastic trichoepithelioma (DTE) is a rare benign adnexal tumor with the characteristic features of asymptomatic, solitary, annular, indurated and centrally depressed papules or plaques, most commonly occurring in younger individuals on the face. Microscopically and clinically, DTE may be difficult to distinguish from other cutaneous adnexal neoplasms, particularly syringoma, cutaneous metastatic breast cancer, morpheaform basal cell carcinoma and microcystic adnexal carcinoma. The present study reports three cases of DTE. The first case was of a 45-year-old male with an asymptomatic flesh-colored plaque below the right edge of the outer canthus that had been present for seven years. The second case was of a 23-year-old female with an asymptomatic skin lesion on the right cheek that had slowly and progressively increased in size. The third case was of a 26-year-old female who presented with a hard yellowish-white plaque, which gradually grew and formed a rectangular, 3×4-cm patch, on the tip of the left brow. This plaque was present for three years without evident cause or subjective symptoms. In all three cases, the routine systemic examinations and laboratory findings were normal. Histopathological and immunohistochemical findings from incisional biopsies of the lesions were consistent with a diagnosis of DTE. DTE treatment methods and immunohistochemical markers were analyzed by reviewing clinical pathological aspects in order to avoid a misdiagnosis and to provide the best available treatment approach for DTE.

Abstract
Microcystic adnexal carcinoma (MAC) is a rare and locally aggressive adenocarcinoma with low-grade malignancy. The present study describes the first reported case and treatment of a Chinese male with a MAC located on the nasal dorsum and nosewing. A 44-year-old man presented with a nasal deformity caused by local repeated infections following an accidental injury to the nose 20 years previously. The nose had been injured by a brick, and treatment at a local hospital 12 years previously had resulted in a nasal scar and a gradually enlarging mass. A physical examination revealed a hypertrophic deformity of the nose and an indurated scar plaque, measuring 2.0×2.0 cm, on the nasal dorsum and nosewing. Microscopic examination revealed a tumor consisting of solid cell nests and a cystic structure with a capsular space. In addition, ductal cells of an adnexal cell origin were visible in the outer epithelium. The medial portion exhibited a microductal structure and invasion of deeper tissues without evident atypia. The tumor cells presented normal nuclear to cytoplasmic ratios and minimal mitotic activity. Pathological examination verified that the tumor was a MAC of low-grade malignancy. A complete surgical resection was performed via Mohs micrographic surgery (MMS), and reconstruction was achieved using an expanded rotational forehead skin flap. No tumor recurrence was detected after a three-year follow-up period. Therefore, for effective treatment of similar MAC cases, complete surgical resection using MMS is recommended, and successful reconstruction may be achieved using an expanded skin flap.

Abstract
BACKGROUND/AIMS Herein, we report a case of microcystic adnexal carcinoma (MAC), which we correlated and evaluated by optical coherence tomography (OCT) and conventional H&E histology. METHODS A commercially available OCT scanner was used for imaging. Several multi-slice images were obtained from the central portion of the lesion. Correlation of OCT findings with histology was performed retrospectively. RESULTS Microcystic adnexal carcinoma showed characteristic criteria, which were divided into superficial and sub-epidermal findings. CONCLUSION The use of OCT can visualize characteristic criteria of MAC, thus enabling prompt diagnosis before surgery.

Abstract
BACKGROUND Desmoplastic trichoepithelioma (DT) is a benign appendageal tumour predominately localized on the facial skin. The histological diagnosis can be difficult in some cases. Partial malignant transformation of a DT is a rarity and a complete transformation has never been described in literature. CASE REPORT A DT of the upper lip was diagnosed histologically by a small biopsy 4 years previously. At presentation, the tumour had enlarged and had partly infiltrated the left side of the upper lip and subnasal region. Histological evaluation confirmed a microcystic adnexal carcinoma but without evidence of malignant transformation of the DT. It appeared that a too-small initial biopsy had led to the incorrect histological diagnosis of a benign tumour. Thus, it was necessary to perform a tumour resection and reconstruction using a two-flap technique including a rotation flap and an Abbé flap. Functional and aesthetic outcomes were good after 6 months. There were no recurrences during a 12-month follow-up. CONCLUSION A facial DT should be resected completely. Patients should be attended for follow-ups, keeping in mind the difficulty of making a proper histological diagnosis from small biopsies or excisions and the consequences of ablative facial surgery. However, in particular cases, subtotal defects of the upper lip region are amenable to reconstruction without gross functional or aesthetic deficits.

Abstract
Giant solitary trichoepithelioma (GST) is a rare trichogenic tumor, which may present as a pigmented lesion. An 80-year-old man was diagnosed to have giant solitary trichoepithelioma on fine-needle aspiration cytology. The cytological findings represented the histological features. The recognition of GST is important because of its close resemblance to basal cell carcinoma and other skin adnexal tumors – clinically, cytologically and histologically.

Abstract
Microcystic adnexal carcinoma (MAC) is an uncommon skin neoplasm with a predilection location around the lips. It is characterized by cords and nests of neoplastic cells forming ductular or glandular structures that are embedded in dense collagenous stroma. An eighty-seven year old Caucasian female patient presented with a painless, slowly enlarging mass measuring 3.3 × 2.7 × 1.0 cm on the lower lip for approximately 6 months. The patient underwent 2 fine needle aspiration biopsies (FNAs). Smears made from both FNAs demonstrated similar features including low cellular smears, three dimensional cell clusters forming a glandular structure, round to oval cells with high N:C ratio, occasional cytoplasmic lumens, without distinct hyperchromasia, focal inconspicuous nucleoli, smooth regular nuclear membranes, abundant naked nuclei, occasional squamoid cells and focal acellular stromal fragments in the background. The cytologic differential diagnosis included skin adnexal carcinoma and low grade mucoepidermoid carcinoma arising in the minor salivary gland. The mass was subsequently excised. The diagnosis of microcystic adnexal carcinoma was made. We report cytologic features of MAC and also suggest that MAC can possibly be diagnosed by FNA with the appropriate clinical vignette and immunohistochemical profile..
